Interesting Natural Number Permutation

Safari seems to do better on this test from a math contest, although the script does not look very heavily optimized.



In a way it is sort of like a performance speed test, since it reports milliseconds required to perform the calculations.

Default N = 5.



Try setting N = 7 or N = 8 if you want to have a larger test.

    28 ms when N = 5



    203 ms when N = 6



    1300 ms when N = 7



    11700 ms when N = 8



    This is in Safari.

    N = 5

    Okay, this is a 1.6 GHz G5 and Safari:



    N = 5 yields 18 ms



    N = 8 yields 5846 ms



    What computer you run makes the most difference.

    Beige 266 G3, iCab



    n = 5 gave 426 to 432 ms (I ran it three times).



    However, these were deeply meaningful milliseconds and I will cherish them forever. I pitty you folks who can't share so much time with your Mac!

    My setup is an AMD Athlon XP 1.6GHz running Mozilla Firebird



    N = 5 : 31 ms



    N = 8 : 13265 ms





    That 1.6GHz G5 earlier in the thread is wicked fast!

    Pentium 4 2.53GHz laptop

    IE6



    N=5 10ms

    N=6 70ms

    N=7 450ms

    N=8 3876ms



    I'll try my single 1.25 Ghz Power Mac later

    It would be interesting to know what is being tested? Let's just look at N = 8 results. A 1.6 GHz Athlon XP using Mozilla Firebird took about 13.3 seconds, but a 2.53GHz Pentium 4 laptop using IE 6 took only 3.9 seconds. The math is trivial, just a single multiply in a loop repeated 8 times. On the PowerBook, Safari took 8.5 seconds, Netscape 7.1 took 41.4 seconds and IE 5.23 took 118.7 seconds.

    Tonight I also ran the same test on the same computer running IE 6 instead



    N = 5 : 15 ms



    N = 8 : 6063 ms



    So IE seems a lot more optimized for this task than Mozilla was. Also Safari seems speedy.
