STINNER Victor added the comment: "If revert c1a698edfa1b, the performance is returned to the level of 3.5."
Oh, so using "fastcall" makes partial_call() slower? That's really something bad :-/ It would be nice if you can confirm using all optimizations enabled (PGO+LTO): ./configure --with-optimizations. For faster compilation and best performances, you might also try to modify PROFILE_TASK in Makefile.pre.in to run your microbenchmark (but you need to run it long enough, so the compiler is able to detect hot code). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28243> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
