Start with src/benchmarks/real-world/bepuphysics2/GatherScatterBenchmarks.cs and GroupedCollisionTesterBenchmarks.cs, then run the provided benchmarks_ci.py commands with the listed filters. Compare the reported Windows/x64 results with the linked baseline and test commits; completion is not defined because the issue reports improvements without specifying a code change.
