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
