Start with the benchmark sources named in src/benchmarks/real-world/bepuphysics2/SweepBenchmarks.cs, GroupedCollisionTesterBenchmarks.cs, TwoBodyConstraintBenchmarks.cs, and GatherScatterBenchmarks.cs, then run the provided benchmarks_ci.py filters. Compare the listed baseline and test reports to confirm the four improvements; done requires triaging whether any follow-up change is needed.
