This comprehensive performance analysis compares react-freeze against custom freeze implementations and a no-optimization baseline. The results demonstrate that react-freeze provides superior performance across all metrics, with 8x faster frozen rendering and 3.6x fewer total renders compared to no optimization.
- Performance Tester: Custom React.Profiler-based measurement system
- Test Environment: React Native Android app
- Metrics Collected: Render time, render count, freeze status
- Data Collection: 5 different implementations tested with identical usage patterns
