Start with the benchmark sources at src/benchmarks/real-world/bepuphysics2/GroupedCollisionTesterBenchmarks.cs and TwoBodyConstraintBenchmarks.cs, then read the benchmarking workflow linked in the issue. Run the provided filtered benchmarks and compare the baseline and test reports to determine whether the measured improvements require follow-up; completion is a confirmed triage result, since no code change is specified.
