Raymond Hettinger added the comment: A C-accelerator should ALWAYS be able to beat a pure python version if it does the same steps but without the overhead of the eval-loop. And in special cases such as type(self)==Counter, it can do much better.
To resolve this report, the C accelerator needs to be fixed. As Stefan pointed-out, the fast-path isn't being triggered because of PyDict_CheckExact test. And, the fallback path can be sped-up as well (by doing the same steps in C as are being done with the pure python code). ---------- stage: -> needs patch versions: +Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18594> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
