Hey everyone,
I've recently looked into building CPython on Windows with GCC+PGO+LTO and it helped quite a bit with the pyperformance benchmark suite compared to a plain build and compared to the official CPython Windows build, see:
https://github.com/msys2/MINGW-packages/pull/5630#issuecomment-514069618
That made me wonder if the official Windows installer uses PGO? If not, maybe it should :)
The official installer it built using Visual Studio and it should be built using PGO (I didn't check).
