Start with docs/benchmarking-workflow-dotnet-runtime.md and run scripts/benchmarks_ci.py using the two filters in the issue. Compare the reported F# and PaintDotNet startup results with the baseline and comparison commits, then inspect the linked benchmark reports. Done means the regressions are reproduced and their cause is identified with an appropriate fix or triage outcome.
