Antoine Pitrou added the comment: Microbenchmarking hash computation (Linux, gcc 4.7.3):
* Short strings: python -m timeit -s "b=b'x'*20" "hash(memoryview(b))" - 64-bit build, before: 0.263 usec per loop - 64-bit build, after: 0.263 usec per loop - 32-bit build, before: 0.303 usec per loop - 32-bit build, after: 0.358 usec per loop * Long strings: python -m timeit -s "b=b'x'*1000" "hash(memoryview(b))" - 64-bit build, before: 1.56 usec per loop - 64-bit build, after: 1.03 usec per loop - 32-bit build, before: 1.61 usec per loop - 32-bit build, after: 2.46 usec per loop Overall, performance looks fine to me. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19183> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
