Start with src/benchmarks/real-world/Akade.IndexedSet.Benchmarks/RangeIndexBenchmarks.cs and reproduce the reported benchmark using scripts/benchmarks_ci.py with the provided filter. Compare the baseline and test commits and inspect the linked benchmark and test reports. Done means the Windows/x64 Min_IndexedSet regression is explained and the benchmark no longer shows the reported slowdown.
