    I read an article about TUX in the dutch C'T a few months ago (nov/dec
    2000, I think) - the real difference (according to the article) was the
    2.2.x kernel used in TUX. Look at the stats of the website, they used
    Redhat 7.0 as base, with kernel 2.2.16. In the C'T, they also used a
    2.4-test kernel for TUX, and this one didn't have these "scalibility
    problems". The problem seemed to be SMP problems with systems with more
    than two cpus in the 2.2.x-based kernel series. 2.4.x kernels didn't
    seem to have this problem.

    And as far as I know, TUX with 2.4.x kernel was faster than win2k on all
