Alexander Belopolsky <[EMAIL PROTECTED]> added the comment: Just to quantify the improvement:
Before: $ ./python -m timeit -s"x='abc'" "x[::-1]" 1000000 loops, best of 3: 0.305 usec per loop $ ./python -O -m timeit -s"x='abc'" "x[::-1]" 1000000 loops, best of 3: 0.275 usec per loop After: $ ./python -m timeit -s"x='abc'" "x[::-1]" 1000000 loops, best of 3: 0.262 usec per loop $ ./python -O -m timeit -s"x='abc'" "x[::-1]" 1000000 loops, best of 3: 0.253 usec per loop For some reason, when I run pybench, the timings vary from run to run so much that I cannot even tell the difference. (Run to run differences are larger than patched to original.) FWIW, the micro-benchmark above shows 8% improvement with "-O" and 14% improvement without. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2268> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
