We are talking about a difference of 157 nanoseconds. On the same laptop, a Python function call which does nothing already takes 76.6 ns +- 4.1 ns. So the overhead of my PR 4489 is the cost of two Python function calls which do nothing. Do you think that it's an inacceptable overhead? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue27535> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
