Start with the benchmark source files linked in the report: src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, GroupedCollisionTesterBenchmarks.cs, and OneBodyConstraintBenchmarks.cs. Run the provided benchmarks_ci.py command with the listed filters, then compare the reported results with the linked test reports. Done means identifying whether these auto-filed improvements require a tracked change or can be closed as expected performance variation.
