Research direction

Start with the provided benchmarks_ci.py commands and the linked performance reports for SDK MSTest, F# Console, and Inner Loop MVC. Compare the baseline and test results on Windows x86, then inspect the referenced baseline and compare commits to identify what changed. Done means the reported performance differences are reproduced and their cause or disposition is documented.
