Start with the linked benchmark source, src/benchmarks/micro/libraries/System.Net.Primitives/CredentialCacheTests.cs, and compare the baseline and comparison commits. Run the provided benchmarks_ci.py command with the CredentialCacheTests filter, then use the linked test and performance reports to investigate the GetCredential_Uri regression. Done means the regression is explained and addressed or otherwise documented.
