Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and GroupedCollisionTesterBenchmarks.cs, then run the provided benchmarks_ci.py commands on Windows. Compare the reported baseline and test durations and review the linked test reports. Done means reproducing and documenting the two benchmark improvements or identifying why they occurred.
