Research direction

Start with the benchmark sources src/benchmarks/real-world/bepuphysics2/GatherScatterBenchmarks.cs, SweepBenchmarks.cs, and GroupedCollisionTesterBenchmarks.cs, then run the listed benchmarks_ci.py commands on Ubuntu. Compare the reported baseline and test measurements with the linked reports and commits; done means determining whether the improvements are reproducible and what follow-up is needed.
