Start with the MicroBenchmarks.FSharp.Collections+CollectionsBenchmark.ArrayRemoveAtEnd benchmark and the provided benchmarks_ci.py command, then compare the linked baseline and test commits and inspect the regression report. Use the benchmarking workflow documentation and report links to determine the cause; done means the regression is explained and its resolution or follow-up is recorded.
