Research direction

Start with the linked benchmarking-workflow-dotnet-runtime.md and profiling-workflow-dotnet-runtime.md documents, then run the three benchmarks with the provided benchmarks_ci.py commands. Compare the reported baseline and test results with the linked reports; the issue does not define a concrete code change or completion criterion, so triage must establish what action, if any, is needed.
