Start by reviewing the linked benchmark reports and source files GroupedCollisionTesterBenchmarks.cs, OneBodyConstraintBenchmarks.cs, and GatherScatterBenchmarks.cs. Run the supplied benchmarks_ci.py commands and compare the reported baseline and test timings. Done means determining whether these automated performance improvements identify an actionable change; the issue does not specify one.
