Hm, that benchmark seems really noisy. Looking at your code, it appears that you aren't actually iterating over the results. I've attached a version of your benchmark rewritten to use pyperf. Here are the results on a system with a fresh PGO/LTO build of CPython main, run with CPU isolation: (py) bucher@is-bucher-p1:~/src/patmaperformance$ sudo $(which pyperf) system tune > /dev/null (py) bucher@is-bucher-p1:~/src/patmaperformance$ sudo $(which python) if_match.py --rigorous ......................................... if: Mean +- std dev: 2.16 ms +- 0.13 ms ......................................... match: Mean +- std dev: 2.13 ms +- 0.07 ms It appears that there is no significant difference between the two (which is what I expect, given the current implementation). With that said, our work in issue 44283 will likely have a significant impact for cases like this. ---------- Added file: https://bugs.python.org/file50083/if_match.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44276> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
