Ben Hoyt added the comment: Some folks have asked about benchmarks. I don't know about iterdir() vs listdir() -- I kind of suspect the speed gains there wouldn't be big.
However, the reason I'm keen on iterdir_stat() is that I'm seeing it speed up os.walk() by a factor of 10 in my recent tests (note that I've made local mods, so these results aren't reproducible for others yet). This is doing a walk on a dir tree with 7800 files and 155 dirs: Using fast _betterwalk Priming the system's cache... Benchmarking walks on C:\Work\betterwalk\benchtree, repeat 1/3... Benchmarking walks on C:\Work\betterwalk\benchtree, repeat 2/3... Benchmarking walks on C:\Work\betterwalk\benchtree, repeat 3/3... os.walk took 0.178s, BetterWalk took 0.017s -- 10.5x as fast Sometimes Windows will go into this "I'm really caching stat results good" mode -- I don't know what heuristic determines this -- and then I'm seeing a 40x speed increase. And no, you didn't read that wrong. :-) Sorry, I'm getting carried away. This bug is really more about iterdir. But seeing Martin suggested the stat/d_type info... ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11406> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
