Research direction

Start with scripts/benchmarks_ci.py and the benchmarking workflow linked in the report, then run the provided filter for the affected SDK template benchmark on Windows/x86. Compare the baseline and test results to identify an actionable SDK change; done means the benchmark result is reproduced and the reported improvement is explained or addressed.

Written by the indexing model from the issue text.
