Quoting Steve Dower <steve.do...@microsoft.com>:
As a Windows user, it makes me wonder if compiling with the latest
version of the Microsoft compiler
would improve things similarly?
I'd expect to see some improvement, based solely on the bugs fixed
recently by the optimizer team. No idea how much, but I know that
Martin builds with PGO, and that's also been improved recently.
I would not expect to see any improvement, unfortunately. I used to
build with PGO, but the recent VS releases miscompiled code, which
was very hard to track down. So PGO has lost in my view for at least
3 VS releases :-(
(Though updating project files to that is almost certainly a bigger
project than the gcc update.)
No idea what the gcc update involved, but this is only accurate if
it took less than two minutes :-) I've upgraded the CPython projects
before and everything worked fine.
Still, we couldn't release 2.7 with any other compiler because of the CRT
dependency.
Regards,
Martin
