    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

    while(count++ < LOTS) {

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