64bit pyperformance results on my Windows 10 PC (dusty i5-4570 CPU) run with--fast --affinity 0 for commit9db1a29 with
- Microsoft Visual Studio 2022 17.13.0 Preview 5.0 which can do PGO again (Remove #pragma that disables optimization on _PyEval_EvalFrameDefault on MSVC #129244)
- which ships with clang-cl 19.1.1
