majiayu000 Performance Benchmark
This skill runs performance benchmarks to measure simulation speed and detect performance regressions.
Usage
Automatically invoked when:
- User asks to benchmark or test performance
- After optimization work
- Comparing performance before/after changes
- Validating that refactoring didn't slow down simulation
Benchmark Tests
Test 1: Braitenberg Extended Run
cd build
time timeout 120s ./bin/yars --iterations 10000 --xml ../xml/braitenberg_logging.xml
Test 2: Falling Objects Physics Test
cd build
time timeout 120s ./bin/yars --iterations 10000 --xml ../xml/falling_objects.xml
Success Criteria
- ✅ Simulations complete without timeout
- ✅ Time measurements recorded
- ✅ Performance within acceptable range
- ✅ No crashes during extended runs
Reporting
Reports should include:
- Real/user/sys time for each test
- Iterations per second
- Comparison with previous benchmarks if available
- Any performance degradation warnings
Notes
- Should be run with release build for accurate results
- Use timeout to prevent runaway simulations
- Benchmark results vary by hardware
- Track trends over time rather than absolute values
