New submission from Stefan Behnel: The method lookup fast path in _PyType_Lookup() does not apply during type creation, which is highly dominated by the performance of the dict lookups along the mro chain. Pre-calculating the name hash speeds up the creation of an empty class (i.e. "class Test: pass") by around 20%.
Will send a pull request shortly. ---------- components: Interpreter Core messages: 301213 nosy: scoder priority: normal severity: normal status: open title: Speed up _PyType_Lookup() for class creation type: performance versions: Python 3.7 _______________________________________ 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
