Research direction

Start with the run information and baseline/compare commits, then inspect the referenced benchmark entries in src/benchmarks/micro/libraries/System.Net.Security/SslStreamTests.cs, SslStreamTests.Context.cs, and SslStreamTests.Protocols.cs. Re-run the listed Linux/x64 Mono benchmarks and compare the results; done means identifying and documenting an actionable cause for the reported improvements.
