Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and reproduce the listed benchmarks with scripts/benchmarks_ci.py using the provided filter. Compare the linked report and benchmark results to determine whether the improvement needs investigation or a code change; the issue does not define a requested change or a concrete done condition.
