$ ./python -S -m timeit -s 'import sys' 'import keyword; keyword=None; del sys.modules["keyword"]' 10000 loops, best of 3: 149 usec per loop Python patched with keyword_grammar.patch: $ ./python -S -m timeit -s 'import sys' 'import keyword; keyword=None; del sys.modules["keyword"]' 10000 loops, best of 3: 20 usec per loop The gain is 129 microseconds (import 7.4x faster). Python starts in between 8,850 and 13,800 microseconds on my PC: $ ./python -S -m timeit -s 'import subprocess; args=[sys.executable, "-S", "-c", "pass"]' 'subprocess.call(args)' 100 loops, best of 3: 8.85 msec per loop $ ./python -S -m timeit -s 'import subprocess; args=[sys.executable, "-c", "pass"]' 'subprocess.call(args)' 100 loops, best of 3: 13.8 msec per loop ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19230> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
