Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, then run the provided benchmarks_ci.py command for the DistanceServo benchmark. Compare the baseline and compare commits and use the linked benchmark and test reports to investigate the regression; done requires a reproducible result and a documented cause or resolution.
