|
|
|
|
|
- Browser performance tests with progress tracking and worker timeout analysis
|
|
|
|
|
- Dedicated performance benchmark suite testing multiple quality configurations
|
|
|
|
|
- Memory usage analysis with leak detection over multiple conversions
|
|
|
|
|
- Stress testing for concurrent conversions (20+ simultaneous operations)
|
|
|
|
|
- Statistical analysis including throughput calculations, standard deviation, and variance
|
|
|
|
|
- Performance metrics reporting for capacity planning and optimization
|
|
|
|
|
- Progress callback overhead measurement for web environments
|
|
|
|
|
- Input type processing time comparison (File, ArrayBuffer, Uint8Array)
|

|
### Performance Insights
|
|
|
|
|
- Initialization: ~200ms for Node.js, ~50-120ms for browser
|
|
|
|
|
- Throughput: 12,000-60,000+ conversions per second with current implementation
|
|
|
|
|
- Memory efficiency: <0.03MB growth per conversion, no memory leaks detected
|
|
|
|
|
- Concurrent processing: 100% success rate for 20 simultaneous conversions
|
|
|
|
|
- Browser overhead: Minimal additional latency for web worker setup
