Start with the linked performance reports and the baseline/compare commit diff, then reproduce using performance/scripts/benchmarks_ci.py with the provided PaintDotNet and VB template filters. Compare the Windows/x64 startup results against the baseline and profiling workflow; done means the three reported regressions are explained and the affected benchmarks no longer regress.
