Start with the linked System.Net.Primitives.Tests.CredentialCacheTests benchmark source and the provided test report, then reproduce it with the benchmarks_ci.py command for the named filter. Compare the arm64 Ubuntu 22.04 baseline and test results to determine whether the reported improvement is actionable; done means the performance change has been validated and its cause or follow-up is clear.
