Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and GroupedCollisionTesterBenchmarks.cs at the linked benchmark ranges, then run the provided benchmarks_ci.py commands on Windows/x64. Use the linked test reports and baseline/compare commits to investigate both regressions; the issue does not define a specific fix or acceptance criteria.
