Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs at the five linked benchmark ranges and review the benchmark and test reports. Run the provided benchmarks_ci.py command, then compare the baseline and test results for the Ubuntu 22.04 tiered configuration. Done requires a confirmed explanation or follow-up for the reported improvements.
