Issues with LTO:

What are the reasons it is ignored? IIRC some compilers have buggy LTO
There is already a ./configure --with-lto flag, why not using it?
I'm using --with-lto without PGO for months, I never noticed that the
option is fully ignored!

I don't know whether it is beneficial or not - but having the capability to
build LTO without PGO seems reasonable. I can review any pull requests altering

I don't think that PGO compilation itself is slow. Basically, I expect that it

In this context, I will be more than happy to receive more feedback and

I've personally never seen a situation where PGO is not desired yet some
other fancier optimization such as LTO is. When do you encounter people
wanting that? PGO always produces a 10-20% faster CPython interpreter.
I have no problem with patches enabling an LTO only build for anyone who
wants on

Hi guys! This is my first post on this list.
I'd like have your opinion on how to safely implement WSGI on a production
server.
My benchmarks show no performance differences between our PHP and Python
environments. I'm using mod_wsgi v3.4 with Apache 2.4.
Is that ok or can it get faster?
