Research direction

Start with the linked benchmark sources, src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs and ShapeRayBenchmarks.cs, then review GatherScatterBenchmarks.cs and the reported benchmark and test reports. Run the provided benchmarks_ci.py command on Ubuntu to reproduce the measurements. Done should include identifying and resolving the cause of the reported performance change, though the issue does not specify a target fix.
