The slow-down is impressive in relative terms (6x) but the timings are still small in absolute value: $ ./python -m timeit -s "f=open('/dev/null', 'a', buffering=4096)" "f.write('log message\n')" 10000000 loops, best of 3: 0.156 usec per loop $ ./python -m timeit -s "f=open('/dev/null', 'a', buffering=1)" "f.write('log message\n')" 1000000 loops, best of 3: 0.961 usec per loop ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13601> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
