IMHO this change is too young to be backported to Python 2.7. I wrote it for Python 3.6 only. For Python 2.7, I suggest to write patches with narrow scope, as you did for the patch only modifying the list type. """ Table 1: CPython 3 GUPB results ------------------------------- unpickle_list 22.74% mako_v2 9.13% nqueens 6.32% meteor_contest 5.61% fannkuch 5.34% simple_logging 5.28% formatted_logging 5.06% """ I surprised to see slow-down, but I prefer to think that changes smaller than 5% are pure noise. The good news is the long list of benchmarks with speedup larger than 5.0% :-) 22% on unpick list is nice to have too! ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26249> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
