Stefan Behnel added the comment: It's the slot names in "slotdefs". See "update_one_slot()".
The time that is saved is mostly the overhead of calling PyDict_GetItem(). I actually tried PyDict_GetItemWithError() first, which is faster due to the lower error handling overhead, before I noticed that the real problem is the repeated lookups of the same name, which can be optimised further by pre-calculating the hash and calling the low-level lookup function. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31336> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
