Research direction

Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs at the cited LinearAxisServo and AngularHinge ranges, then run the provided benchmarks_ci.py command. Compare the reported Windows/x64 results with the linked baseline and test commits. The issue does not define a requested code change or clear completion condition; triage should first establish what action is expected.
