If put a bytes object into multiple dicts/sets, the hash need to be computed multiple times. This seems a common usage. bytes is a very basic type, users may use it in various ways. And unskilled users may checking the same bytes object against dicts/sets many times. FYI, 1 GiB data: function seconds hash() 0.40 binascii.crc32() 1.66 (Gregory P. Smith is trying to improve this) zlib.crc32() 0.65 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46864> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
