Start with the benchmark sources src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and GatherScatterBenchmarks.cs, then run scripts/benchmarks_ci.py with the filters shown in the issue. Compare the reported baseline and test results using the linked reports; done means confirming the improvements and determining the appropriate follow-up.
