Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs at the linked benchmark ranges, then run the provided benchmarks_ci.py command using the documented benchmarking workflow. Compare the SwingLimit, AngularHinge, and Contact4Nonconvex results with the linked report; done requires determining whether the reported improvements need follow-up, since no code change is specified.
