Start with the benchmark sources at src/benchmarks/micro/libraries/Microsoft.Extensions.Caching.Memory/MemoryCacheTests.cs and ScopesOverheadBenchmark.cs, then run the two provided benchmarks with benchmarks_ci.py. Compare the reported results with the linked baseline and test commits; done means validating the improvements and determining whether any follow-up investigation is needed.
