I made simple, approximate measurements with an empty class: - fixup_slot_dispatchers() takes 78% of the time (!) - __build_class__() takes 5% - computing the default __qualname__, __module__, __doc__ takes 3% - set_names() takes 2.5% - init_subclass() takes 2.5% Regards Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
