Start by comparing the linked baseline and test commits, then inspect the benchmark sources at src/benchmarks/real-world/bepuphysics2/SweepBenchmarks.cs, GroupedCollisionTesterBenchmarks.cs, GatherScatterBenchmarks.cs, and TwoBodyConstraintBenchmarks.cs. Run the listed benchmarks_ci.py commands and review the linked test reports; done means determining whether the reported improvements are expected and documenting the finding or a concrete follow-up.
