random_bench.py has really weird timings. Example: (...) Run 15: 1 warmup, 3 values, 2^15 loops - warmup 1: 3.05 us (+504%) - value 1: 42.8 ns (-92%) - value 2: 1.18 us (+133%) - value 3: 293 ns (-42%) (...) Run 21: 1 warmup, 3 values, 2^15 loops - warmup 1: 167 us (+1073%) - value 1: 162 ns (-99%) - value 2: 39.1 us (+174%) - value 3: 3.53 us (-75%) needle=3: Mean +- std dev: 17.2 us +- 39.6 us How is it possible that in the same process (same "Run"), timing changes between 42 ns and 1 180 ns? The std dev is really large. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41972> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
