STINNER Victor added the comment: Maybe we should investigate more optimizations on specialized lists.
PyPy uses a more compact structure for lists of integers for example. Something like compact strings, PEP 393, of Python 3.3, but for lists. http://doc.pypy.org/en/latest/interpreter-optimizations.html#list-optimizations But we are limited by the C API, so we cannot change deeply the C structure without breaking backward compatibility. > # (difference is within std dev) You can use perf timeit --compare-to to check if the result is significant or not, and it displays you the "N.NNx faster" or "N.NNx slower" if it's significant. About benchmarks, I also would like to see a benchmark on the bad case, when specialization is not used. And not only on an empty list :-) For example, sort 1000 objects which implement compare operators and/or a sort function. ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28685> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
