Research direction

Start with the referenced benchmarking-workflow-dotnet-runtime.md and run scripts/benchmarks_ci.py using the listed benchmark filters on Windows. Compare the baseline and test results for the four startup scenarios; the issue does not specify a code location or acceptance criteria, so the cause and definition of done still need triage.

Written by the indexing model from the issue text.
