Research direction

Start with docs/benchmarking-workflow-dotnet-runtime.md, then run scripts/benchmarks_ci.py using the Windows command and benchmark filter provided for each reported scenario. Review the linked test reports and compare the baseline and test measurements to determine whether the startup changes are reproducible and what follow-up is warranted; the issue does not define a specific code change or completion condition.
