Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and GatherScatterBenchmarks.cs at the linked lines, then run the provided benchmarks_ci.py commands. Review the linked performance reports and compare the baseline and test results; the issue does not define a code change or acceptance criterion beyond investigating these reported improvements.
