This can easily happen as a result of different memory layout, but is very much dependent on the machine architecture, CPU, memory type, etc. > Dict microbenchmarks: > > DictCreation: 38ms 36ms +4.8% 39ms 37ms +3.9% > DictWithFloatKeys: 40ms 40ms -0.8% 40ms 40ms -0.4% > DictWithIntegerKeys: 33ms 31ms +7.2% 33ms 31ms +7.6% > DictWithStringKeys: 29ms 28ms +0.4% 29ms 29ms +0.7% > SimpleDictManipulation: 59ms 59ms -0.4% 59ms 59ms -0.4% Only dict creation and the integer keys benchmark results are relevant. Could you perhaps check what's causing these slowdowns ? ---------- nosy: +lemburg _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26058> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
