Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and OneBodyConstraintBenchmarks.cs, then run the provided benchmarks_ci.py commands on Windows. Compare the reported benchmark results with the linked baseline and comparison commits, and use the profiling and benchmarking workflow docs to investigate the regression. Done means identifying and addressing the cause of the four reported performance regressions, then confirming the benchmarks no longer regress.
