I wrote PR 25393 to micro-optimize _PyType_GetModuleByDef(). It reduces the overhead from +5.7 ns to +3.4 ns (-2.3 ns). Well, I didn't check in depth if _PyType_GetModuleByDef() is the only change in functools.lru_cache() from Python 3.9 to master. Compare master to Python 3.9: Mean +- std dev: [py39] 37.5 ns +- 1.0 ns -> [master] 43.2 ns +- 0.7 ns: 1.15x slower Compare PR 25393 to Python 3.9: Mean +- std dev: [py39] 37.5 ns +- 1.0 ns -> [inline] 40.9 ns +- 1.0 ns: 1.09x slower Compare PR 25393 to master: Mean +- std dev: [master] 43.2 ns +- 0.7 ns -> [inline] 40.9 ns +- 1.0 ns: 1.05x faster ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40137> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
