32-bit and 64-bit are in reverse. I compared b1 and a7 because this can be
confirmed by anyone with official binary. If 7% of my patch has little to do
with the gap, then I will be happy that 3.10 can be far faster.
>How can I build Python with PGO on Windows?
Try the following,
PCbuild\build.bat -p x64 --no-tkinter --pgo
Before building, your object.h needs to replace
static inline int Py_ALWAYS_INLINE
with
static Py_ALWAYS_INLINE int
In my case, pgo got stuck on linking with the object.h.
I'm waiting the reply from developercommunity.
