I attached a minimal C extension module that can be used to demonstrate the performance degradation from Python 3.7.0a3 to 3.7.0a4. Build the extension with `py setup.py build_ext --inplace`, then run the following code on Python 3.7.0a3 to 3.7.0a4: ``` import time from test_isdigit import test_isdigit start_time = time.time() test_isdigit() print(time.time() - start_time) ``` On my Windows 10 Pro WS system, the timings are: Python 3.7.0a3: ~0.0156 Python 3.7.0a4: ~0.3281 I would expect that other locale aware functions in the UCRT are also affected but I have not tested that. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35195> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
