Start with performance/scripts/benchmarks_ci.py and the benchmarking workflow linked in the issue, then run the three provided filters on Windows x86. Compare the baseline and test commits using the linked reports and diff. Done means the regressions are reproduced, their cause is identified, and the affected benchmark results are validated after the fix.
