Research direction

Start with scripts/benchmarks_ci.py and the documented benchmarking workflow, then run the listed Windows x86 filters for the four benchmark names. Compare the linked baseline and test reports to determine whether any improvement needs a code change; the issue provides no source file, failing test, or concrete requested behavior, so completion is not defined.
