Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs at the linked benchmark ranges, then run the provided benchmarks_ci.py command using the DemoBenchmarks.TwoBodyConstraintBenchmarks filter. Compare the results with the listed baseline and test commits and inspect the linked test report; done means establishing whether the four measured improvements require follow-up.
