Research direction

Start with the benchmarking workflow document and reproduce the three reported cases using scripts/benchmarks_ci.py with the listed filters. Compare the supplied baseline and compare commits and review the linked benchmark reports for the Windows/x86 results. Done means determining whether these measurements require an actionable performance fix; the issue does not name a target file or change.
