Start with the linked benchmarking workflow documentation and run scripts/benchmarks_ci.py using the two filters in the issue on Windows x64. Review the PaintDotNet and Static Winforms Template reports and compare the baseline and test results. Done means identifying and addressing the cause of the reported startup performance change, with benchmark results confirming the outcome.
