Start with src/benchmarks/micro/libraries/System.Net.Primitives/CredentialCacheTests.cs, especially the GetCredential_Uri benchmark, and run the documented benchmarks_ci.py command with its filter. Compare the reported ARM64 AzureLinux result with the linked baseline and test commits; done means identifying whether the improvement needs a corresponding runtime change or further triage.
