Start with scripts/benchmarks_ci.py and the benchmarking workflow linked in the issue, then run the two supplied filters on Windows/x64. Compare the baseline and comparison commits and review the linked performance reports for the VB console and PaintDotNet startup regressions. Done means the cause is identified and a rerun verifies the reported regressions are resolved or explained.
