Pablo Galindo Salgado <pablog...@gmail.com> added the comment: Here are some benchmarks of using lru_cache in 3.9 and 3.10 (PGO/LTO/CPU isol):
❯ ./python -m pyperf timeit "from functools import lru_cache; f = lru_cache(lambda: 42)" "f()" --compare-to ../3.9/python /home/pablogsal/github/3.9/python: ..................... 2.60 us +- 0.05 us /home/pablogsal/github/cpython/python: ..................... 2.74 us +- 0.06 us Mean +- std dev: [/home/pablogsal/github/3.9/python] 2.60 us +- 0.05 us -> [/home/pablogsal/github/cpython/python] 2.74 us +- 0.06 us: 1.06x slower Given that lru_cache is normally used to seek speed, this is a bit unfortunate :( ---------- _______________________________________ 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
