Start with src/benchmarks/real-world/Akade.IndexedSet.Benchmarks/RangeIndexBenchmarks.cs and FullTextIndexBenchmarks.cs at the linked benchmark lines, then run the two provided benchmarks_ci.py filters. Compare the baseline and test results and inspect the linked performance reports; done means the reported regressions are understood and the affected benchmark no longer regresses.
