Start with the benchmark sources in src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, SweepBenchmarks.cs, and GroupedCollisionTesterBenchmarks.cs, then reproduce with scripts/benchmarks_ci.py using the reported filters. Compare the listed baseline and test results and inspect the linked reports and profiling workflow. Done means the reported regressions are explained and the affected benchmarks no longer regress.
