Oh ok, sure.

I am not sure that I want to use PGO compilation to run benchmarks. Last time I checked, I noticed performance differences between two compilations. PGO compilation doesn't seem 100% deterministic. Maybe PGO compilation is fine when you build Python to create a Linux package. But to get reliable benchmarks, I'm not sure that it's a good idea. I'm still running benchmarks on Python recompiled many times using different compiler options, to measure the impact of the compiler options (especially LTO and/or PGO) on the benchmark stability. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28618> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
