    No it measures the performance of the "time()" call. Windows has some
    funky optimisations that we never bother with because time() isn't a hot
    path in the real world.

    Instead try code which does


    time(&start);
    while(count++ < LOTS) {
    Do_stuff
    }
    time(&end)

    and you'll find the numbers on pure CPU work are essentially CPU bound
    not OS affected at all
