Start with src/benchmarks/real-world/bepuphysics2/SweepBenchmarks.cs and TwoBodyConstraintBenchmarks.cs at the linked benchmark lines, then run the listed benchmarks_ci.py commands. Compare the baseline and test commits using the linked reports and profiling workflow docs. Done means explaining the CapsuleCylinder and BallSocket regressions and documenting the resulting diagnosis or fix.
