Oh. There is a bit of confusion here. You must *not* run directly bm_xxx.py scripts. The calibration is done in perf.py. Try for example: python perf.py python2 python3 -b json_dump_v2 You must see something like: Calibrating => num_runs=10, num_loops=16 (0.50 sec < 0.55 sec) I should maybe share the calibration code to also compute the number of iterations when a bm_xxx.py script is run directly? But the risk is that someone compares two runs of bm_xxx.py using two python binaries, and seeing different results just because the number of calibrated loops is different... ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26275> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
