+# SmartProxy Byte Counting Audit Report
+
+## Executive Summary
+
+After a comprehensive audit of the SmartProxy codebase, I can confirm that **byte counting is implemented correctly** with no instances of double counting. Each byte transferred through the proxy is counted exactly once in each direction.
+
+## Byte Counting Implementation
+
+### 1. Core Tracking Mechanisms
+
+SmartProxy uses two complementary tracking systems:
+
+1. **Connection Records** (`IConnectionRecord`):
+   - `bytesReceived`: Total bytes received from client
+   - `bytesSent`: Total bytes sent to client
+
+2. **MetricsCollector**:
+   - Global throughput tracking via `ThroughputTracker`
+   - Per-connection byte tracking for route/IP metrics
+   - Called via `recordBytes(connectionId, bytesIn, bytesOut)`
+
+### 2. Where Bytes Are Counted
+
+Bytes are counted in only two files:
+
+#### a) `route-connection-handler.ts`
+- **Line 351**: TLS alert bytes when no SNI is provided
+- **Lines 1286-1301**: Data forwarding callbacks in `setupBidirectionalForwarding()`
+
+#### b) `http-proxy-bridge.ts`  
+- **Line 127**: Initial TLS chunk for HttpProxy connections
+- **Lines 142-154**: Data forwarding callbacks in `setupBidirectionalForwarding()`
+
+## Connection Flow Analysis
+
+### 1. Direct TCP Connection (No TLS)
+
+```
+Client → SmartProxy → Target Server
+```
+
+1. Connection arrives at `RouteConnectionHandler.handleConnection()`
+2. For non-TLS ports, immediately routes via `routeConnection()`
+3. `setupDirectConnection()` creates target connection
+4. `setupBidirectionalForwarding()` handles all data transfer:
+   - `onClientData`: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
+   - `onServerData`: `bytesSent += chunk.length` + `recordBytes(0, chunk.length)`
+
+**Result**: ✅ Each byte counted exactly once
+
+### 2. TLS Passthrough Connection
+
+```
+Client (TLS) → SmartProxy → Target Server (TLS)
+```
+
+1. Connection waits for initial data to detect TLS
+2. TLS handshake detected, SNI extracted
+3. Route matched, `setupDirectConnection()` called
+4. Initial chunk stored in `pendingData` (NOT counted yet)
+5. On target connect, `pendingData` written to target (still not counted)
+6. `setupBidirectionalForwarding()` counts ALL bytes including initial chunk
+
+**Result**: ✅ Each byte counted exactly once
+
+### 3. TLS Termination via HttpProxy
+
+```
+Client (TLS) → SmartProxy → HttpProxy (localhost) → Target Server
+```
+
+1. TLS connection detected with `tls.mode = "terminate"`
+2. `forwardToHttpProxy()` called:
+   - Initial chunk: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
+3. Proxy connection created to HttpProxy on localhost
+4. `setupBidirectionalForwarding()` handles subsequent data
+
+**Result**: ✅ Each byte counted exactly once
+
+### 4. HTTP Connection via HttpProxy
+
+```
+Client (HTTP) → SmartProxy → HttpProxy (localhost) → Target Server
+```
+
+1. Connection on configured HTTP port (`useHttpProxy` ports)
+2. Same flow as TLS termination
+3. All byte counting identical to TLS termination
+
+**Result**: ✅ Each byte counted exactly once
+
+### 5. NFTables Forwarding
+
+```
+Client → [Kernel NFTables] → Target Server
+```
+
+1. Connection detected, route matched with `forwardingEngine: 'nftables'`
+2. Connection marked as `usingNetworkProxy = true`
+3. NO application-level forwarding (kernel handles packet routing)
+4. NO byte counting in application layer
+
+**Result**: ✅ No counting (correct - kernel handles everything)
+
+## Special Cases
+
+### PROXY Protocol
+- PROXY protocol headers sent to backend servers are NOT counted in client metrics
+- Only actual client data is counted
+- **Correct behavior**: Protocol overhead is not client data
+
+### TLS Alerts
+- TLS alerts (e.g., for missing SNI) are counted as sent bytes
+- **Correct behavior**: Alerts are actual data sent to the client
+
+### Initial Chunks
+- **Direct connections**: Stored in `pendingData`, counted when forwarded
+- **HttpProxy connections**: Counted immediately upon receipt
+- **Both approaches**: Count each byte exactly once
+
+## Verification Methodology
+
+1. **Code Analysis**: Searched for all instances of:
+   - `bytesReceived +=` and `bytesSent +=`
+   - `recordBytes()` calls
+   - Data forwarding implementations
+
+2. **Flow Tracing**: Followed data path for each connection type from entry to exit
+
+3. **Handler Review**: Examined all forwarding handlers to ensure no additional counting
+
+## Findings
+
+### ✅ No Double Counting Detected
+
+- Each byte is counted exactly once in the direction it flows
+- Connection records and metrics are updated consistently
+- No overlapping or duplicate counting logic found
+
+### Areas of Excellence
+
+1. **Centralized Counting**: All byte counting happens in just two files
+2. **Consistent Pattern**: Uses `setupBidirectionalForwarding()` with callbacks
+3. **Clear Separation**: Forwarding handlers don't interfere with proxy metrics
+
+## Recommendations
+
+1. **Debug Logging**: Add optional debug logging to verify byte counts in production:
+   ```typescript
+   if (settings.debugByteCount) {
+     logger.log('debug', `Bytes counted: ${connectionId} +${bytes} (total: ${record.bytesReceived})`);
+   }
+   ```
+
+2. **Unit Tests**: Create specific tests to ensure byte counting accuracy:
+   - Test initial chunk handling
+   - Test PROXY protocol overhead exclusion
+   - Test HttpProxy forwarding accuracy
+
+3. **Protocol Overhead Tracking**: Consider separately tracking:
+   - PROXY protocol headers
+   - TLS handshake bytes
+   - HTTP headers vs body
+
+4. **NFTables Documentation**: Clearly document that NFTables-forwarded connections are not included in application metrics
+
+## Conclusion
+
+SmartProxy's byte counting implementation is **robust and accurate**. The design ensures that each byte is counted exactly once, with clear separation between connection tracking and metrics collection. No remediation is required.

-# SmartProxy Project Hints
-
-## Project Overview
-- Package: `@push.rocks/smartproxy` – high-performance proxy supporting HTTP(S), TCP, WebSocket, and ACME integration.
-- Written in TypeScript, compiled output in `dist_ts/`, uses ESM with NodeNext resolution.
-
-## Important: ACME Configuration in v19.0.0
-- **Breaking Change**: ACME configuration must be placed within individual route TLS settings, not at the top level
-- Route-level ACME config is the ONLY way to enable SmartAcme initialization
-- SmartCertManager requires email in route config for certificate acquisition
-- Top-level ACME configuration is ignored in v19.0.0
-
-## Repository Structure
-- `ts/` – TypeScript source files:
-  - `index.ts` exports main modules.
-  - `plugins.ts` centralizes native and third-party imports.
-  - Subdirectories: `networkproxy/`, `nftablesproxy/`, `port80handler/`, `redirect/`, `smartproxy/`.
-  - Key classes: `ProxyRouter` (`classes.router.ts`), `SmartProxy` (`classes.smartproxy.ts`), plus handlers/managers.
-- `dist_ts/` – transpiled `.js` and `.d.ts` files mirroring `ts/` structure.
-- `test/` – test suites in TypeScript:
-  - `test.router.ts` – routing logic (hostname matching, wildcards, path parameters, config management).
-  - `test.smartproxy.ts` – proxy behavior tests (TCP forwarding, SNI handling, concurrency, chaining, timeouts).
-  - `test/helpers/` – utilities (e.g., certificates).
-- `assets/certs/` – placeholder certificates for ACME and TLS.
-
-## Development Setup
-- Requires `pnpm` (v10+).
-- Install dependencies: `pnpm install`.
-- Build: `pnpm build` (runs `tsbuild --web --allowimplicitany`).
-- Test: `pnpm test` (runs `tstest test/`).
-- Format: `pnpm format` (runs `gitzone format`).
-
-## How to Test
-
-### Test Structure
-Tests use tapbundle from `@git.zone/tstest`. The correct pattern is:
-
-```typescript
-import { tap, expect } from '@git.zone/tstest/tapbundle';
-
-tap.test('test description', async () => {
-  // Test logic here
-  expect(someValue).toEqual(expectedValue);
-});
-
-// IMPORTANT: Must end with tap.start()
-tap.start();
-```
-
-### Expect Syntax (from @push.rocks/smartexpect)
-```typescript
-// Type assertions
-expect('hello').toBeTypeofString();
-expect(42).toBeTypeofNumber();
-
-// Equality
-expect('hithere').toEqual('hithere');
-
-// Negated assertions
-expect(1).not.toBeTypeofString();
-
-// Regular expressions
-expect('hithere').toMatch(/hi/);
-
-// Numeric comparisons
-expect(5).toBeGreaterThan(3);
-expect(0.1 + 0.2).toBeCloseTo(0.3, 10);
-
-// Arrays
-expect([1, 2, 3]).toContain(2);
-expect([1, 2, 3]).toHaveLength(3);
-
-// Async assertions
-await expect(asyncFunction()).resolves.toEqual('expected');
-await expect(asyncFunction()).resolves.withTimeout(5000).toBeTypeofString();
-
-// Complex object navigation
-expect(complexObject)
-  .property('users')
-  .arrayItem(0)
-  .property('name')
-  .toEqual('Alice');
-```
-
-### Test Modifiers
-- `tap.only.test()` - Run only this test
-- `tap.skip.test()` - Skip a test
-- `tap.timeout()` - Set test-specific timeout
-
-### Running Tests
-- All tests: `pnpm test`
-- Specific test: `tsx test/test.router.ts`
-- With options: `tstest test/**/*.ts --verbose --timeout 60`
-
-### Test File Requirements
-- Must start with `test.` prefix
-- Must use `.ts` extension
-- Must call `tap.start()` at the end
-
-## Coding Conventions
-- Import modules via `plugins.ts`:
-  ```ts
-  import * as plugins from './plugins.ts';
-  const server = new plugins.http.Server();
-  ```
-- Reference plugins with full path: `plugins.acme`, `plugins.smartdelay`, `plugins.minimatch`, etc.
-- Path patterns support globs (`*`) and parameters (`:param`) in `ProxyRouter`.
-- Wildcard hostname matching leverages `minimatch` patterns.
-
-## Key Components
-- **ProxyRouter**
-  - Methods: `routeReq`, `routeReqWithDetails`.
-  - Hostname matching: case-insensitive, strips port, supports exact, wildcard, TLD, complex patterns.
-  - Path routing: exact, wildcard, parameter extraction (`pathParams`), returns `pathMatch` and `pathRemainder`.
-  - Config API: `setNewProxyConfigs`, `addProxyConfig`, `removeProxyConfig`, `getHostnames`, `getProxyConfigs`.
-- **SmartProxy**
-  - Manages one or more `net.Server` instances to forward TCP streams.
-  - Options: `preserveSourceIP`, `defaultAllowedIPs`, `globalPortRanges`, `sniEnabled`.
-  - DomainConfigManager: round-robin selection for multiple target IPs.
-  - Graceful shutdown in `stop()`, ensures no lingering servers or sockets.
-
-## Notable Points
-- **TSConfig**: `module: NodeNext`, `verbatimModuleSyntax`, allows `.js` extension imports in TS.
-- Mermaid diagrams and architecture flows in `readme.md` illustrate component interactions and protocol flows.
-- CLI entrypoint (`cli.js`) supports command-line usage (ACME, proxy controls).
-- ACME and certificate handling via `Port80Handler` and `helpers.certificates.ts`.
-
-## ACME/Certificate Configuration Example (v19.0.0)
-```typescript
-const proxy = new SmartProxy({
-  routes: [{
-    name: 'example.com',
-    match: { domains: 'example.com', ports: 443 },
-    action: {
-      type: 'forward',
-      target: { host: 'localhost', port: 8080 },
-      tls: {
-        mode: 'terminate',
-        certificate: 'auto',
-        acme: {  // ACME config MUST be here, not at top level
-          email: 'ssl@example.com',
-          useProduction: false,
-          challengePort: 80
-        }
-      }
-    }
-  }]
-});
-```
-
-## TODOs / Considerations
-- Ensure import extensions in source match build outputs (`.ts` vs `.js`).
-- Update `plugins.ts` when adding new dependencies.
-- Maintain test coverage for new routing or proxy features.
-- Keep `ts/` and `dist_ts/` in sync after refactors.
-- Consider implementing top-level ACME config support for backward compatibility
-
-## HTTP-01 ACME Challenge Fix (v19.3.8)
-
-### Issue
-Non-TLS connections on ports configured in `useHttpProxy` were not being forwarded to HttpProxy. This caused ACME HTTP-01 challenges to fail when the ACME port (usually 80) was included in `useHttpProxy`.
-
-### Root Cause
-In the `RouteConnectionHandler.handleForwardAction` method, only connections with TLS settings (mode: 'terminate' or 'terminate-and-reencrypt') were being forwarded to HttpProxy. Non-TLS connections were always handled as direct connections, even when the port was configured for HttpProxy.
-
-### Solution
-Added a check for non-TLS connections on ports listed in `useHttpProxy`:
-```typescript
-// No TLS settings - check if this port should use HttpProxy
-const isHttpProxyPort = this.settings.useHttpProxy?.includes(record.localPort);
-
-if (isHttpProxyPort && this.httpProxyBridge.getHttpProxy()) {
-  // Forward non-TLS connections to HttpProxy if configured
-  this.httpProxyBridge.forwardToHttpProxy(/*...*/);
-  return;
-}
-```
-
-### Test Coverage
-- `test/test.http-fix-unit.ts` - Unit tests verifying the fix
-- Tests confirm that non-TLS connections on HttpProxy ports are properly forwarded
-- Tests verify that non-HttpProxy ports still use direct connections
-
-### Configuration Example
-```typescript
-const proxy = new SmartProxy({
-  useHttpProxy: [80], // Enable HttpProxy for port 80
-  httpProxyPort: 8443,
-  acme: {
-    email: 'ssl@example.com',
-    port: 80
-  },
-  routes: [
-    // Your routes here
-  ]
-});
-```
-
-## ACME Certificate Provisioning Timing Fix (v19.3.9)
-
-### Issue
-Certificate provisioning would start before ports were listening, causing ACME HTTP-01 challenges to fail with connection refused errors.
-
-### Root Cause
-SmartProxy initialization sequence:
-1. Certificate manager initialized → immediately starts provisioning
-2. Ports start listening (too late for ACME challenges)
-
-### Solution
-Deferred certificate provisioning until after ports are ready:
-```typescript
-// SmartCertManager.initialize() now skips automatic provisioning
-// SmartProxy.start() calls provisionAllCertificates() directly after ports are listening
-```
-
-### Test Coverage
-- `test/test.acme-timing-simple.ts` - Verifies proper timing sequence
-
-### Migration
-Update to v19.3.9+, no configuration changes needed.
-
-## Socket Handler Race Condition Fix (v19.5.0)
-
-### Issue
-Initial data chunks were being emitted before async socket handlers had completed setup, causing data loss when handlers performed async operations before setting up data listeners.
-
-### Root Cause
-The `handleSocketHandlerAction` method was using `process.nextTick` to emit initial chunks regardless of whether the handler was sync or async. This created a race condition where async handlers might not have their listeners ready when the initial data was emitted.
-
-### Solution
-Differentiated between sync and async handlers:
-```typescript
-const result = route.action.socketHandler(socket);
-
-if (result instanceof Promise) {
-  // Async handler - wait for completion before emitting initial data
-  result.then(() => {
-    if (initialChunk && initialChunk.length > 0) {
-      socket.emit('data', initialChunk);
-    }
-  }).catch(/*...*/);
-} else {
-  // Sync handler - use process.nextTick as before
-  if (initialChunk && initialChunk.length > 0) {
-    process.nextTick(() => {
-      socket.emit('data', initialChunk);
-    });
-  }
-}
-```
-
-### Test Coverage
-- `test/test.socket-handler-race.ts` - Specifically tests async handlers with delayed listener setup
-- Verifies that initial data is received even when handler sets up listeners after async work
-
-### Usage Note
-Socket handlers require initial data from the client to trigger routing (not just a TLS handshake). Clients must send at least one byte of data for the handler to be invoked.
-
-## Route-Specific Security Implementation (v19.5.3)
-
-### Issue
-Route-specific security configurations (ipAllowList, ipBlockList, authentication) were defined in the route types but not enforced at runtime.
-
-### Root Cause
-The RouteConnectionHandler only checked global IP validation but didn't enforce route-specific security rules after matching a route.
-
-### Solution
-Added security checks after route matching:
-```typescript
-// Apply route-specific security checks
-const routeSecurity = route.action.security || route.security;
-if (routeSecurity) {
-  // Check IP allow/block lists
-  if (routeSecurity.ipAllowList || routeSecurity.ipBlockList) {
-    const isIPAllowed = this.securityManager.isIPAuthorized(
-      remoteIP,
-      routeSecurity.ipAllowList || [],
-      routeSecurity.ipBlockList || []
-    );
-    
-    if (!isIPAllowed) {
-      socket.end();
-      this.connectionManager.cleanupConnection(record, 'route_ip_blocked');
-      return;
-    }
-  }
-}
-```
-
-### Test Coverage
-- `test/test.route-security-unit.ts` - Unit tests verifying SecurityManager.isIPAuthorized logic
-- Tests confirm IP allow/block lists work correctly with glob patterns
-
-### Configuration Example
-```typescript
-const routes: IRouteConfig[] = [{
-  name: 'secure-api',
-  match: { ports: 8443, domains: 'api.example.com' },
-  action: {
-    type: 'forward',
-    target: { host: 'localhost', port: 3000 },
-    security: {
-      ipAllowList: ['192.168.1.*', '10.0.0.0/8'],    // Allow internal IPs
-      ipBlockList: ['192.168.1.100'],                // But block specific IP
-      maxConnections: 100,                            // Per-route limit (TODO)
-      authentication: {                               // HTTP-only, requires TLS termination
-        type: 'basic',
-        credentials: [{ username: 'api', password: 'secret' }]
-      }
-    }
-  }
-}];
-```
-
-### Notes
-- IP lists support glob patterns (via minimatch): `192.168.*`, `10.?.?.1`
-- Block lists take precedence over allow lists
-- Authentication requires TLS termination (cannot be enforced on passthrough/direct connections)
-- Per-route connection limits are not yet implemented
-- Security is defined at the route level (route.security), not in the action
-- Route matching is based solely on match criteria; security is enforced after matching
-
-## Performance Issues Investigation (v19.5.3+)
-
-### Critical Blocking Operations Found
-1. **Busy Wait Loop** in `ts/proxies/nftables-proxy/nftables-proxy.ts:235-238`
-   - Blocks entire event loop with `while (Date.now() < waitUntil) {}`
-   - Should use `await new Promise(resolve => setTimeout(resolve, delay))`
-
-2. **Synchronous Filesystem Operations**
-   - Certificate management uses `fs.existsSync()`, `fs.mkdirSync()`, `fs.readFileSync()`
-   - NFTables proxy uses `execSync()` for system commands
-   - Certificate store uses `ensureDirSync()`, `fileExistsSync()`, `removeManySync()`
-
-3. **Memory Leak Risks**
-   - Several `setInterval()` calls without storing references for cleanup
-   - Event listeners added without proper cleanup in error paths
-   - Missing `removeAllListeners()` calls in some connection cleanup scenarios
-
-### Performance Recommendations
-- Replace all sync filesystem operations with async alternatives
-- Fix the busy wait loop immediately (critical event loop blocker)
-- Add proper cleanup for all timers and event listeners
-- Consider worker threads for CPU-intensive operations
-- See `readme.problems.md` for detailed analysis and recommendations
-
-## Performance Optimizations Implemented (Phase 1 - v19.6.0)
-
-### 1. Async Utilities Created (`ts/core/utils/async-utils.ts`)
-- **delay()**: Non-blocking alternative to busy wait loops
-- **retryWithBackoff()**: Retry operations with exponential backoff
-- **withTimeout()**: Execute operations with timeout protection
-- **parallelLimit()**: Run async operations with concurrency control
-- **debounceAsync()**: Debounce async functions
-- **AsyncMutex**: Ensure exclusive access to resources
-- **CircuitBreaker**: Protect against cascading failures
-
-### 2. Filesystem Utilities Created (`ts/core/utils/fs-utils.ts`)
-- **AsyncFileSystem**: Complete async filesystem operations
-  - exists(), ensureDir(), readFile(), writeFile()
-  - readJSON(), writeJSON() with proper error handling
-  - copyFile(), moveFile(), removeDir()

-## Socket Error Handling Fix (v19.5.11+)
-
-### Issue
-Server crashed with unhandled 'error' event when backend connections failed (ECONNREFUSED). Also caused memory leak with rising active connection count as failed connections weren't cleaned up properly.
-
-### Root Cause
-1. **Race Condition**: In forwarding handlers, sockets were created with `net.connect()` but error handlers were attached later, creating a window where errors could crash the server
-2. **Incomplete Cleanup**: When server connections failed, client sockets weren't properly cleaned up, leaving connection records in memory
-
-### Solution
-Created `createSocketWithErrorHandler()` utility that attaches error handlers immediately:
-```typescript
-// Before (race condition):
-const socket = net.connect(port, host);
-// ... other code ...
-socket.on('error', handler); // Too late!
-
-// After (safe):
-const socket = createSocketWithErrorHandler({
-  port, host,
-  onError: (error) => {
-    // Handle error immediately
-    clientSocket.destroy();
-  },
-  onConnect: () => {
-    // Set up forwarding
-  }
-});
-```
-
-### Changes Made
-1. **New Utility**: `ts/core/utils/socket-utils.ts` - Added `createSocketWithErrorHandler()`
-2. **Updated Handlers**:
-   - `https-passthrough-handler.ts` - Uses safe socket creation
-   - `https-terminate-to-http-handler.ts` - Uses safe socket creation
-3. **Connection Cleanup**: Client sockets destroyed immediately on server connection failure
-
-### Test Coverage
-- `test/test.socket-error-handling.node.ts` - Verifies server doesn't crash on ECONNREFUSED
-- `test/test.forwarding-error-fix.node.ts` - Tests forwarding handlers handle errors gracefully
+# SmartProxy Development Hints
+
+## Byte Tracking and Metrics
+
+### Throughput Drift Issue (Fixed)
+
+**Problem**: Throughput numbers were gradually increasing over time for long-lived connections.
+
+**Root Cause**: The `byRoute()` and `byIP()` methods were dividing cumulative total bytes (since connection start) by the window duration, causing rates to appear higher as connections aged:
+- Hour 1: 1GB total / 60s = 17 MB/s ✓
+- Hour 2: 2GB total / 60s = 34 MB/s ✗ (appears doubled!)
+- Hour 3: 3GB total / 60s = 50 MB/s ✗ (keeps rising!)
+
+**Solution**: Implemented dedicated ThroughputTracker instances for each route and IP address:
+- Each route and IP gets its own throughput tracker with per-second sampling
+- Samples are taken every second and stored in a circular buffer
+- Rate calculations use actual samples within the requested window
+- Default window is now 1 second for real-time accuracy
+
+### What Gets Counted (Network Interface Throughput)
+
+The byte tracking is designed to match network interface throughput (what Unifi/network monitoring tools show):
+
+**Counted bytes include:**
+- All application data
+- TLS handshakes and protocol overhead
+- TLS record headers and encryption padding
+- HTTP headers and protocol data
+- WebSocket frames and protocol overhead
+- TLS alerts sent to clients
+
+**NOT counted:**
+- PROXY protocol headers (sent to backend, not client)
+- TCP/IP headers (handled by OS, not visible at application layer)
+
+**Byte direction:**
+- `bytesReceived`: All bytes received FROM the client on the incoming connection
+- `bytesSent`: All bytes sent TO the client on the incoming connection
+- Backend connections are separate and not mixed with client metrics
+
+### Double Counting Issue (Fixed)
+
+**Problem**: Initial data chunks were being counted twice in the byte tracking:
+1. Once when stored in `pendingData` in `setupDirectConnection()`
+2. Again when the data flowed through bidirectional forwarding
+
+**Solution**: Removed the byte counting when storing initial chunks. Bytes are now only counted when they actually flow through the `setupBidirectionalForwarding()` callbacks.
+
+### HttpProxy Metrics (Fixed)
+
+**Problem**: HttpProxy forwarding was updating connection record byte counts but not calling `metricsCollector.recordBytes()`, resulting in missing throughput data.
+
+**Solution**: Added `metricsCollector.recordBytes()` calls to the HttpProxy bidirectional forwarding callbacks.
+
+### Metrics Architecture
+
+The metrics system has multiple layers:
+1. **Connection Records** (`record.bytesReceived/bytesSent`): Track total bytes per connection
+2. **Global ThroughputTracker**: Accumulates bytes between samples for overall rate calculations
+3. **Per-Route ThroughputTrackers**: Dedicated tracker for each route with per-second sampling
+4. **Per-IP ThroughputTrackers**: Dedicated tracker for each IP with per-second sampling
+5. **connectionByteTrackers**: Track cumulative bytes and metadata for active connections
+
+Key features:
+- All throughput trackers sample every second (1Hz)
+- Each tracker maintains a circular buffer of samples (default: 1 hour retention)
+- Rate calculations are accurate for any requested window (default: 1 second)
+- All byte counting happens exactly once at the data flow point
+- Unused route/IP trackers are automatically cleaned up when connections close
+
+### Understanding "High" Byte Counts
+
+If byte counts seem high compared to actual application data, remember:
+- TLS handshakes can be 1-5KB depending on cipher suites and certificates
+- Each TLS record has 5 bytes of header overhead
+- TLS encryption adds 16-48 bytes of padding/MAC per record
+- HTTP/2 has additional framing overhead
+- WebSocket has frame headers (2-14 bytes per message)
+
+This overhead is real network traffic and should be counted for accurate throughput metrics.
+
+### Byte Counting Paths
+
+There are two mutually exclusive paths for connections:
+
+1. **Direct forwarding** (route-connection-handler.ts):
+   - Used for TCP passthrough, TLS passthrough, and direct connections
+   - Bytes counted in `setupBidirectionalForwarding` callbacks
+   - Initial chunk NOT counted separately (flows through bidirectional forwarding)
+
+2. **HttpProxy forwarding** (http-proxy-bridge.ts):
+   - Used for TLS termination (terminate, terminate-and-reencrypt)
+   - Initial chunk counted when written to proxy
+   - All subsequent bytes counted in `setupBidirectionalForwarding` callbacks
+   - This is the ONLY counting point for these connections
+
+### Byte Counting Audit (2025-01-06)
+
+A comprehensive audit was performed to verify byte counting accuracy:
+
+**Audit Results:**
+- ✅ No double counting detected in any connection flow
+- ✅ Each byte counted exactly once in each direction
+- ✅ Connection records and metrics updated consistently
+- ✅ PROXY protocol headers correctly excluded from client metrics
+- ✅ NFTables forwarded connections correctly not counted (kernel handles)
+
+**Key Implementation Points:**
+- All byte counting happens in only 2 files: `route-connection-handler.ts` and `http-proxy-bridge.ts`
+- Both use the same pattern: increment `record.bytesReceived/Sent` AND call `metricsCollector.recordBytes()`
+- Initial chunks handled correctly: stored but not counted until forwarded
+- TLS alerts counted as sent bytes (correct - they are sent to client)
+
+For full audit details, see `readme.byte-counting-audit.md`
+
+## Connection Cleanup
+
+### Zombie Connection Detection
+
+The connection manager performs comprehensive zombie detection every 10 seconds:
+- **Full zombies**: Both incoming and outgoing sockets destroyed but connection not cleaned up
+- **Half zombies**: One socket destroyed, grace period expired (5 minutes for TLS, 30 seconds for non-TLS)
+- **Stuck connections**: Data received but none sent back after threshold (5 minutes for TLS, 60 seconds for non-TLS)
+
+### Cleanup Queue
+
+Connections are cleaned up through a batched queue system:
+- Batch size: 100 connections
+- Processing triggered immediately when batch size reached
+- Otherwise processed after 100ms delay
+- Prevents overwhelming the system during mass disconnections
+
+## Keep-Alive Handling
+
+Keep-alive connections receive special treatment based on `keepAliveTreatment` setting:
+- **standard**: Normal timeout applies
+- **extended**: Timeout multiplied by `keepAliveInactivityMultiplier` (default 6x)
+- **immortal**: No timeout, connections persist indefinitely
+
+## PROXY Protocol
+
+The system supports both receiving and sending PROXY protocol:
+- **Receiving**: Automatically detected from trusted proxy IPs (configured in `proxyIPs`)
+- **Sending**: Enabled per-route or globally via `sendProxyProtocol` setting
+- Real client IP is preserved and used for all connection tracking and security checks
+
+## Metrics and Throughput Calculation
+
+The metrics system tracks throughput using per-second sampling:
+
+1. **Byte Recording**: Bytes are recorded as data flows through connections
+2. **Sampling**: Every second, accumulated bytes are stored as a sample
+3. **Rate Calculation**: Throughput is calculated by summing bytes over a time window
+4. **Per-Route/IP Tracking**: Separate ThroughputTracker instances for each route and IP
+
+Key implementation details:
+- Bytes are recorded in the bidirectional forwarding callbacks
+- The instant() method returns throughput over the last 1 second
+- The recent() method returns throughput over the last 10 seconds
+- Custom windows can be specified for different averaging periods
+
+### Throughput Spikes Issue
+
+There's a fundamental difference between application-layer and network-layer throughput:
+
+**Application Layer (what we measure)**:
+- Bytes are recorded when delivered to/from the application
+- Large chunks can arrive "instantly" due to kernel/Node.js buffering
+- Shows spikes when buffers are flushed (e.g., 20MB in 1 second = 160 Mbit/s)
+
+**Network Layer (what Unifi shows)**:
+- Actual packet flow through the network interface
+- Limited by physical network speed (e.g., 20 Mbit/s)
+- Data transfers over time, not in bursts
+
+The spikes occur because:
+1. Data flows over network at 20 Mbit/s (takes 8 seconds for 20MB)
+2. Kernel/Node.js buffers this incoming data
+3. When buffer is flushed, application receives large chunk at once
+4. We record entire chunk in current second, creating artificial spike
+
+**Potential Solutions**:
+1. Use longer window for "instant" measurements (e.g., 5 seconds instead of 1)
+2. Track socket write backpressure to estimate actual network flow
+3. Implement bandwidth estimation based on connection duration
+4. Accept that application-layer != network-layer throughput
+
+## Connection Limiting
+
+### Per-IP Connection Limits
+- SmartProxy tracks connections per IP address in the SecurityManager
+- Default limit is 100 connections per IP (configurable via `maxConnectionsPerIP`)
+- Connection rate limiting is also enforced (default 300 connections/minute per IP)
+- HttpProxy has been enhanced to also enforce per-IP limits when forwarding from SmartProxy
+
+### Route-Level Connection Limits
+- Routes can define `security.maxConnections` to limit connections per route
+- ConnectionManager tracks connections by route ID using a separate Map
+- Limits are enforced in RouteConnectionHandler before forwarding
+- Connection is tracked when route is matched: `trackConnectionByRoute(routeId, connectionId)`
+
+### HttpProxy Integration
+- When SmartProxy forwards to HttpProxy for TLS termination, it sends a `CLIENT_IP:<ip>\r\n` header
+- HttpProxy parses this header to track the real client IP, not the localhost IP
+- This ensures per-IP limits are enforced even for forwarded connections
+- The header is parsed in the connection handler before any data processing
+
+### Memory Optimization
+- Periodic cleanup runs every 60 seconds to remove:
+  - IPs with no active connections
+  - Expired rate limit timestamps (older than 1 minute)
+- Prevents memory accumulation from many unique IPs over time
+- Cleanup is automatic and runs in background with `unref()` to not keep process alive
+
+### Connection Cleanup Queue
+- Cleanup queue processes connections in batches to prevent overwhelming the system
+- Race condition prevention using `isProcessingCleanup` flag
+- Try-finally block ensures flag is always reset even if errors occur
+- New connections added during processing are queued for next batch
+
+### Important Implementation Notes
+- Always use `NodeJS.Timeout` type instead of `NodeJS.Timer` for interval/timeout references
+- IPv4/IPv6 normalization is handled (e.g., `::ffff:127.0.0.1` and `127.0.0.1` are treated as the same IP)
+- Connection limits are checked before route matching to prevent DoS attacks
+- SharedSecurityManager supports checking route-level limits via optional parameter
+
+## Log Deduplication
+
+To reduce log spam during high-traffic scenarios or attacks, SmartProxy implements log deduplication for repetitive events:
+
+### How It Works
+- Similar log events are batched and aggregated over a 5-second window
+- Instead of logging each event individually, a summary is emitted
+- Events are grouped by type and deduplicated by key (e.g., IP address, reason)
+
+### Deduplicated Event Types
+1. **Connection Rejections** (`connection-rejected`):
+   - Groups by rejection reason (global-limit, route-limit, etc.)
+   - Example: "Rejected 150 connections (reasons: global-limit: 100, route-limit: 50)"
+
+2. **IP Rejections** (`ip-rejected`):
+   - Groups by IP address
+   - Shows top offenders with rejection counts and reasons
+   - Example: "Rejected 500 connections from 10 IPs (top offenders: 192.168.1.100 (200x, rate-limit), ...)"
+
+3. **Connection Cleanups** (`connection-cleanup`):
+   - Groups by cleanup reason (normal, timeout, error, zombie, etc.)
+   - Example: "Cleaned up 250 connections (reasons: normal: 200, timeout: 30, error: 20)"
+
+4. **IP Tracking Cleanup** (`ip-cleanup`):
+   - Summarizes periodic IP cleanup operations
+   - Example: "IP tracking cleanup: removed 50 entries across 5 cleanup cycles"
 
 ### Configuration
-No configuration changes needed. The fix is transparent to users.
+- Default flush interval: 5 seconds
+- Maximum batch size: 100 events (triggers immediate flush)
+- Global periodic flush: Every 10 seconds (ensures logs are emitted regularly)
+- Process exit handling: Logs are flushed on SIGINT/SIGTERM
 
-### Important Note
-The fix was applied in two places:
-1. **ForwardingHandler classes** (`https-passthrough-handler.ts`, etc.) - These are standalone forwarding utilities
-2. **SmartProxy route-connection-handler** (`route-connection-handler.ts`) - This is where the actual SmartProxy connection handling happens
+### Benefits
+- Reduces log volume during attacks or high traffic
+- Provides better overview of patterns (e.g., which IPs are attacking)
+- Improves log readability and analysis
+- Prevents log storage overflow
+- Maintains detailed information in aggregated form
 
-The critical fix for SmartProxy was in `setupDirectConnection()` method in route-connection-handler.ts, which now uses `createSocketWithErrorHandler()` to properly handle connection failures and clean up connection records.
+### Log Output Examples
 
-## Connection Cleanup Improvements (v19.5.12+)
-
-### Issue
-Connections were still counting up during rapid retry scenarios, especially when routing failed or backend connections were refused. This was due to:
-1. **Delayed Cleanup**: Using `initiateCleanupOnce` queued cleanup operations (batch of 100 every 100ms) instead of immediate cleanup
-2. **NFTables Memory Leak**: NFTables connections were never cleaned up, staying in memory forever
-3. **Connection Limit Bypass**: When max connections reached, connection record check happened after creation
-
-### Root Cause Analysis
-1. **Queued vs Immediate Cleanup**:
-   - `initiateCleanupOnce()`: Adds to cleanup queue, processes up to 100 connections every 100ms
-   - `cleanupConnection()`: Immediate synchronous cleanup
-   - Under rapid retries, connections were created faster than the queue could process them
-
-2. **NFTables Connections**: 
-   - Marked with `usingNetworkProxy = true` but never cleaned up
-   - Connection records stayed in memory indefinitely
-
-3. **Error Path Cleanup**:
-   - Many error paths used `socket.end()` (async) followed by cleanup
-   - Created timing windows where connections weren't fully cleaned
-
-### Solution
-1. **Immediate Cleanup**: Changed all error paths from `initiateCleanupOnce()` to `cleanupConnection()` for immediate cleanup
-2. **NFTables Cleanup**: Added socket close listener to clean up connection records when NFTables connections close
-3. **Connection Limit Fix**: Added null check after `createConnection()` to handle rejection properly
-
-### Changes Made in route-connection-handler.ts
-```typescript
-// 1. NFTables cleanup (line 551-553)
-socket.once('close', () => {
-  this.connectionManager.cleanupConnection(record, 'nftables_closed');
-});
-
-// 2. Connection limit check (line 93-96)
-const record = this.connectionManager.createConnection(socket);
-if (!record) {
-  // Connection was rejected due to limit - socket already destroyed
-  return;
-}
-
-// 3. Changed all error paths to use immediate cleanup
-// Before: this.connectionManager.initiateCleanupOnce(record, reason)
-// After: this.connectionManager.cleanupConnection(record, reason)
+Instead of hundreds of individual logs:
+```
+Connection rejected
+Connection rejected
+Connection rejected
+... (repeated 500 times)
 ```
 
-### Test Coverage
-- `test/test.rapid-retry-cleanup.node.ts` - Verifies connection cleanup under rapid retry scenarios
-- Test shows connection count stays at 0 even with 20 rapid retries with 50ms intervals
-- Confirms both ECONNREFUSED and routing failure scenarios are handled correctly
+You'll see:
+```
+[SUMMARY] Rejected 500 connections from 10 IPs in 5s (rate-limit: 350, per-ip-limit: 150) (top offenders: 192.168.1.100 (200x, rate-limit), 10.0.0.1 (150x, per-ip-limit))
+```
 
-### Performance Impact
-- **Positive**: No more connection accumulation under load
-- **Positive**: Immediate cleanup reduces memory usage
-- **Consideration**: More frequent cleanup operations, but prevents queue backlog
+Instead of:
+```
+Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 266
+Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 265
+... (repeated 266 times)
+```
 
-### Migration Notes
-No configuration changes needed. The improvements are automatic and backward compatible.
+You'll see:
+```
+[SUMMARY] 266 HttpProxy connections terminated in 5s (reasons: client_closed: 266, activeConnections: 0)
+```
 
-## Early Client Disconnect Handling (v19.5.13+)
+### Rapid Event Handling
+- During attacks or high-volume scenarios, logs are flushed more frequently
+- If 50+ events occur within 1 second, immediate flush is triggered
+- Prevents memory buildup during flooding attacks
+- Maintains real-time visibility during incidents
 
-### Issue
-Connections were accumulating when clients connected but disconnected before sending data or during routing. This occurred in two scenarios:
-1. **TLS Path**: Clients connecting and disconnecting before sending initial TLS handshake data
-2. **Non-TLS Immediate Routing**: Clients disconnecting while backend connection was being established
+## Custom Certificate Provision Function
 
-### Root Cause
-1. **Missing Cleanup Handlers**: During initial data wait and immediate routing, no close/end handlers were attached to catch early disconnections
-2. **Race Condition**: Backend connection attempts continued even after client disconnected, causing unhandled errors
-3. **Timing Window**: Between accepting connection and establishing full bidirectional flow, disconnections weren't properly handled
+The `certProvisionFunction` feature has been implemented to allow users to provide their own certificate generation logic.
 
-### Solution
-1. **TLS Path Fix**: Added close/end handlers during initial data wait (lines 224-253 in route-connection-handler.ts)
-2. **Immediate Routing Fix**: Used `setupSocketHandlers` for proper handler attachment (lines 180-205)
-3. **Backend Error Handling**: Check if connection already closed before handling backend errors (line 1144)
+### Implementation Details
 
-### Changes Made
+1. **Type Definition**: The function must return `Promise<TSmartProxyCertProvisionObject>` where:
+   - `TSmartProxyCertProvisionObject = plugins.tsclass.network.ICert | 'http01'`
+   - Return `'http01'` to fallback to Let's Encrypt
+   - Return a certificate object for custom certificates
+
+2. **Certificate Manager Changes**:
+   - Added `certProvisionFunction` property to CertificateManager
+   - Modified `provisionAcmeCertificate()` to check custom function first
+   - Custom certificates are stored with source type 'custom'
+   - Expiry date extraction currently defaults to 90 days
+
+3. **Configuration Options**:
+   - `certProvisionFunction`: The custom provision function
+   - `certProvisionFallbackToAcme`: Whether to fallback to ACME on error (default: true)
+
+4. **Usage Example**:
 ```typescript
-// 1. TLS path - handle disconnect before initial data
-socket.once('close', () => {
-  if (!initialDataReceived) {
-    this.connectionManager.cleanupConnection(record, 'closed_before_data');
-  }
-});
-
-// 2. Immediate routing path - proper handler setup
-setupSocketHandlers(socket, (reason) => {
-  if (!record.outgoing || record.outgoing.readyState !== 'open') {
-    if (record.outgoing && !record.outgoing.destroyed) {
-      record.outgoing.destroy(); // Abort pending backend connection
+new SmartProxy({
+  certProvisionFunction: async (domain: string) => {
+    if (domain === 'internal.example.com') {
+      return {
+        cert: customCert,
+        key: customKey,
+        ca: customCA
+      } as unknown as TSmartProxyCertProvisionObject;
     }
-    this.connectionManager.cleanupConnection(record, reason);
-  }
-}, undefined, 'immediate-route-client');
-
-// 3. Backend connection error handling
-onError: (error) => {
-  if (record.connectionClosed) {
-    logger.log('debug', 'Backend connection failed but client already disconnected');
-    return; // Client already gone, nothing to clean up
-  }
-  // ... normal error handling
-}
+    return 'http01'; // Use Let's Encrypt
+  },
+  certProvisionFallbackToAcme: true
+})
 ```
 
-### Test Coverage
-- `test/test.connect-disconnect-cleanup.node.ts` - Comprehensive test for early disconnect scenarios
-- Tests verify connection count stays at 0 even with rapid connect/disconnect patterns
-- Covers immediate disconnect, delayed disconnect, and mixed patterns
+5. **Testing Notes**:
+   - Type assertions through `unknown` are needed in tests due to strict interface typing
+   - Mock certificate objects work for testing but need proper type casting
+   - The actual certificate parsing for expiry dates would need a proper X.509 parser
 
-### Performance Impact
-- **Positive**: No more connection accumulation from early disconnects
-- **Positive**: Immediate cleanup reduces memory usage
-- **Positive**: Prevents resource exhaustion from rapid reconnection attempts
+### Future Improvements
 
-### Migration Notes
-No configuration changes needed. The fix is automatic and backward compatible.
-
-## Proxy Chain Connection Accumulation Fix (v19.5.14+)
-
-### Issue
-When chaining SmartProxies (Client → SmartProxy1 → SmartProxy2 → Backend), connections would accumulate and never be cleaned up. This was particularly severe when the backend was down or closing connections immediately.
-
-### Root Cause
-The half-open connection support was preventing proper cascade cleanup in proxy chains:
-1. Backend closes → SmartProxy2's server socket closes
-2. SmartProxy2 keeps client socket open (half-open support)
-3. SmartProxy1 never gets notified that downstream is closed
-4. Connections accumulate at each proxy in the chain
-
-The issue was in `createIndependentSocketHandlers()` which waited for BOTH sockets to close before cleanup.
-
-### Solution
-1. **Changed default behavior**: When one socket closes, both close immediately
-2. **Made half-open support opt-in**: Only enabled when explicitly requested
-3. **Centralized socket handling**: Created `setupBidirectionalForwarding()` for consistent behavior
-4. **Applied everywhere**: Updated HttpProxyBridge and route-connection-handler to use centralized handling
-
-### Changes Made
-```typescript
-// socket-utils.ts - Default behavior now closes both sockets
-export function createIndependentSocketHandlers(
-  clientSocket, serverSocket, onBothClosed,
-  options: { enableHalfOpen?: boolean } = {} // Half-open is opt-in
-) {
-  // When server closes, immediately close client (unless half-open enabled)
-  if (!clientClosed && !options.enableHalfOpen) {
-    clientSocket.destroy();
-  }
-}
-
-// New centralized function for consistent socket pairing
-export function setupBidirectionalForwarding(
-  clientSocket, serverSocket,
-  handlers: {
-    onClientData?: (chunk) => void;
-    onServerData?: (chunk) => void;
-    onCleanup: (reason) => void;
-    enableHalfOpen?: boolean; // Default: false
-  }
-)
-```
-
-### Test Coverage
-- `test/test.proxy-chain-simple.node.ts` - Verifies proxy chains don't accumulate connections
-- Tests confirm connections stay at 0 even with backend closing immediately
-- Works for any proxy chain configuration (not just localhost)
-
-### Performance Impact
-- **Positive**: No more connection accumulation in proxy chains
-- **Positive**: Immediate cleanup reduces memory usage
-- **Neutral**: Half-open connections still available when needed (opt-in)
-
-### Migration Notes
-No configuration changes needed. The fix applies to all proxy chains automatically.
+1. Implement proper certificate expiry date extraction using X.509 parsing
+2. Add support for returning expiry date with custom certificates
+3. Consider adding validation for custom certificate format
+4. Add events/hooks for certificate provisioning lifecycle

+# SmartProxy Enhanced Routing Plan
+
+## Goal
+Implement enhanced routing structure with multiple targets per route, sub-matching capabilities, and target-specific overrides to enable more elegant and DRY configurations.
+
+## Key Changes
+
+### 1. Update Route Target Interface
+- Add `match` property to `IRouteTarget` for sub-matching within routes
+- Add target-specific override properties (tls, websocket, loadBalancing, etc.)
+- Add priority field for controlling match order
+
+### 2. Update Route Action Interface
+- Remove singular `target` property
+- Use only `targets` array (single target = array with one element)
+- Maintain backwards compatibility during migration
+
+### 3. Implementation Steps
+
+#### Phase 1: Type Updates
+- [x] Update `IRouteTarget` interface in `route-types.ts`
+  - Add `match?: ITargetMatch` property
+  - Add override properties (tls, websocket, etc.)
+  - Add `priority?: number` field
+- [x] Create `ITargetMatch` interface for sub-matching criteria
+- [x] Update `IRouteAction` to use only `targets: IRouteTarget[]`
+
+#### Phase 2: Route Resolution Logic
+- [x] Update route matching logic to handle multiple targets
+- [x] Implement target sub-matching algorithm:
+  1. Sort targets by priority (highest first)
+  2. For each target with a match property, check if request matches
+  3. Use first matching target, or fallback to target without match
+- [x] Ensure target-specific settings override route-level settings
+
+#### Phase 3: Code Migration

+## Example Configurations
+
+### Before (Current)
+```typescript
+// Need separate routes for different ports/paths
+[
+  {
+    match: { domains: ['api.example.com'], ports: [80] },
+    action: {
+      type: 'forward',
+      target: { host: 'backend', port: 8080 },
+      tls: { mode: 'terminate' }
+    }
+  },
+  {
+    match: { domains: ['api.example.com'], ports: [443] },
+    action: {
+      type: 'forward',
+      target: { host: 'backend', port: 8081 },
+      tls: { mode: 'passthrough' }
+    }
+  }
+]
+```
+
+### After (Enhanced)
+```typescript
+// Single route with multiple targets
+{
+  match: { domains: ['api.example.com'], ports: [80, 443] },
+  action: {
+    type: 'forward',
+    targets: [
+      {
+        match: { ports: [80] },
+        host: 'backend',
+        port: 8080,
+        tls: { mode: 'terminate' }
+      },
+      {
+        match: { ports: [443] },
+        host: 'backend',
+        port: 8081,
+        tls: { mode: 'passthrough' }
+      }
+    ]
+  }
+}
+```
+
+### Advanced Example
+```typescript
+{
+  match: { domains: ['app.example.com'], ports: [443] },
+  action: {
+    type: 'forward',
+    tls: { mode: 'terminate', certificate: 'auto' }, // Route-level default
+    websocket: { enabled: true }, // Route-level default
+    targets: [
+      {
+        match: { path: '/api/v2/*' },
+        host: 'api-v2',
+        port: 8082,
+        priority: 10
+      },
+      {
+        match: { path: '/api/*', headers: { 'X-Version': 'v1' } },
+        host: 'api-v1',
+        port: 8081,
+        priority: 5
+      },
+      {
+        match: { path: '/ws/*' },
+        host: 'websocket-server',
+        port: 8090,
+        websocket: { 
+          enabled: true,
+          rewritePath: '/'  // Strip /ws prefix
+        }
+      },
+      {
+        // Default target (no match property)
+        host: 'web-backend',
+        port: 8080
+      }
+    ]
+  }
+}
+```
+
+## Benefits
+1. **DRY Configuration**: No need to duplicate common settings across routes
+2. **Flexibility**: Different backends for different ports/paths within same domain
+3. **Clarity**: All routing for a domain in one place
+4. **Performance**: Single route lookup instead of multiple
+5. **Backwards Compatible**: Can migrate gradually
+
+## Migration Strategy
+1. Keep support for `target` temporarily with deprecation warning
+2. Auto-convert `target` to `targets: [target]` internally
+3. Update documentation with migration examples
+4. Remove `target` support in next major version

-# SmartProxy Performance Issues Report
-
-## Executive Summary
-This report identifies performance issues and blocking operations in the SmartProxy codebase that could impact scalability and responsiveness under high load.
-
-## Critical Issues
-
-### 1. **Synchronous Filesystem Operations**
-These operations block the event loop and should be replaced with async alternatives:
-
-#### Certificate Management
-- `ts/proxies/http-proxy/certificate-manager.ts:29`: `fs.existsSync()` 
-- `ts/proxies/http-proxy/certificate-manager.ts:30`: `fs.mkdirSync()`
-- `ts/proxies/http-proxy/certificate-manager.ts:49-50`: `fs.readFileSync()` for loading certificates
-
-#### NFTables Proxy
-- `ts/proxies/nftables-proxy/nftables-proxy.ts`: Multiple uses of `execSync()` for system commands
-- `ts/proxies/nftables-proxy/nftables-proxy.ts`: Multiple `fs.writeFileSync()` and `fs.unlinkSync()` operations
-
-#### Certificate Store
-- `ts/proxies/smart-proxy/cert-store.ts:8`: `ensureDirSync()`
-- `ts/proxies/smart-proxy/cert-store.ts:15,31,76`: `fileExistsSync()`
-- `ts/proxies/smart-proxy/cert-store.ts:77`: `removeManySync()`
-
-### 2. **Event Loop Blocking Operations**
-
-#### Busy Wait Loop
-- `ts/proxies/nftables-proxy/nftables-proxy.ts:235-238`: 
-  ```typescript
-  const waitUntil = Date.now() + retryDelayMs;
-  while (Date.now() < waitUntil) {
-    // busy wait - blocks event loop completely
-  }
-  ```
-  This is extremely problematic as it blocks the entire Node.js event loop.
-
-### 3. **Potential Memory Leaks**
-
-#### Timer Management Issues
-Several timers are created without proper cleanup:
-- `ts/proxies/http-proxy/function-cache.ts`: `setInterval()` without storing reference for cleanup
-- `ts/proxies/http-proxy/request-handler.ts`: `setInterval()` for rate limit cleanup without cleanup
-- `ts/core/utils/shared-security-manager.ts`: `cleanupInterval` stored but no cleanup method
-
-#### Event Listener Accumulation
-- Multiple instances of event listeners being added without corresponding cleanup
-- Connection handlers add listeners without always removing them on connection close
-
-### 4. **Connection Pool Management**
-
-#### ConnectionPool (ts/proxies/http-proxy/connection-pool.ts)
-**Good practices observed:**
-- Proper connection lifecycle management
-- Periodic cleanup of idle connections
-- Connection limits enforcement
-
-**Potential issues:**
-- No backpressure mechanism when pool is full
-- Synchronous sorting operation in `cleanupConnectionPool()` could be slow with many connections
-
-### 5. **Resource Management Issues**
-
-#### Socket Cleanup
-- Some error paths don't properly clean up sockets
-- Missing `removeAllListeners()` in some error scenarios could lead to memory leaks
-
-#### Timeout Management
-- Inconsistent timeout handling across different components
-- Some sockets created without timeout settings
-
-### 6. **JSON Operations on Large Objects**
-- `ts/proxies/smart-proxy/cert-store.ts:21`: `JSON.parse()` on certificate metadata
-- `ts/proxies/smart-proxy/cert-store.ts:71`: `JSON.stringify()` with pretty printing
-- `ts/proxies/http-proxy/function-cache.ts:76`: `JSON.stringify()` for cache keys (called frequently)
-
-## Recommendations
-
-### Immediate Actions (High Priority)
-
-1. **Replace Synchronous Operations**
-   ```typescript
-   // Instead of:
-   if (fs.existsSync(path)) { ... }
-   
-   // Use:
-   try {
-     await fs.promises.access(path);
-     // file exists
-   } catch {
-     // file doesn't exist
-   }
-   ```
-
-2. **Fix Busy Wait Loop**
-   ```typescript
-   // Instead of:
-   while (Date.now() < waitUntil) { }
-   
-   // Use:
-   await new Promise(resolve => setTimeout(resolve, retryDelayMs));
-   ```
-
-3. **Add Timer Cleanup**
-   ```typescript
-   class Component {
-     private cleanupTimer?: NodeJS.Timeout;
-     
-     start() {
-       this.cleanupTimer = setInterval(() => { ... }, 60000);
-     }
-     
-     stop() {
-       if (this.cleanupTimer) {
-         clearInterval(this.cleanupTimer);
-         this.cleanupTimer = undefined;
-       }
-     }
-   }
-   ```
-
-### Medium Priority
-
-1. **Optimize JSON Operations**
-   - Cache JSON.stringify results for frequently used objects
-   - Consider using faster hashing for cache keys (e.g., crypto.createHash)
-   - Use streaming JSON parsers for large objects
-
-2. **Improve Connection Pool**
-   - Implement backpressure/queueing when pool is full
-   - Use a heap or priority queue for connection management instead of sorting
-
-3. **Standardize Resource Cleanup**
-   - Create a base class for components with lifecycle management
-   - Ensure all event listeners are removed on cleanup
-   - Add abort controllers for better cancellation support
-
-### Long-term Improvements
-
-1. **Worker Threads**
-   - Move CPU-intensive operations to worker threads
-   - Consider using worker pools for NFTables operations
-
-2. **Monitoring and Metrics**
-   - Add performance monitoring for event loop lag
-   - Track connection pool utilization
-   - Monitor memory usage patterns
-
-3. **Graceful Degradation**
-   - Implement circuit breakers for backend connections
-   - Add request queuing with overflow protection
-   - Implement adaptive timeout strategies
-
-## Impact Assessment
-
-These issues primarily affect:
-- **Scalability**: Blocking operations limit concurrent connection handling
-- **Responsiveness**: Event loop blocking causes latency spikes
-- **Stability**: Memory leaks could cause crashes under sustained load
-- **Resource Usage**: Inefficient resource management increases memory/CPU usage
-
-## Testing Recommendations
-
-1. Load test with high connection counts (10k+ concurrent)
-2. Monitor event loop lag under stress
-3. Test long-running scenarios to detect memory leaks
-4. Benchmark with async vs sync operations to measure improvement
-
-## Conclusion
-
-While SmartProxy has good architectural design and many best practices, the identified blocking operations and resource management issues could significantly impact performance under high load. The most critical issues (busy wait loop and synchronous filesystem operations) should be addressed immediately.
