-m timeit -s "x=2**40" "x&2;x&2;x&2;x&333;x&3;x&3;x&4444;x&4" with patch: 0.404usec without patch: 0.41 > Does it have effect after applying patches from 24165? I'm not sure how it's related, but let's modify the test to stress the mem allocation: -m timeit -s "x=21827623" "(x+x)&2;(x+x)&2;(x+x)&2;(x+x)&333;(x+x)&3;x&3;(x+x)&4444;(x+x)&4" this patch+freelist: 0.337usec only freelist: 0.496 In any case, bit operations are often used for bit-flags logic, where numbers are usually aren't too big (it's rare to see more than 30 bit flags on one field). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26342> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
