STINNER Victor added the comment: I tested on Linux.
(1) for i in `seq 5`; do ./python -I -m timeit -n1 -r1 -s "import sys; sys.modules.clear()" -- "import enum"; done (shortest timing) Python 3.4: 6.93 msec Python 3.6: 7.05 msec (+2%) (2) for i in `seq 5`; do ./python -I -m timeit "import enum"; done Python 3.4: 0.331 usec Python 3.6: 0.341 usec (+%3) These numbers are nanoseconds, it's too short to run a real benchmark. (3) for i in `seq 5`; do ./python -I -m timeit -n1 -r1 "import enum"; done Python 3.4: 801 usec Python 3.6: 774 usec (-3%) Sorry, I don't see major differences like you showed. Can you explain exactly how to reproduce them? Exact Python version? OS? I used the development branches (branch 3.4 and branch default). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25159> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
