    Ah sorry - I never meant to imply that Tux was detrimental, other
    than one case where it seemed to have no benefit and the performance
    numbers while tuning for TPC-W *seemed* worse but were never analyzed
    completely. That was the actual event that I meant when I said:

    We also had some bad starts with using Tux in terms of performance
    and scalability on 4-CPU and 8-CPU machines, especially when
    combining with things like squid or other cacheing products from
    various third parties.

    Those results were never quantified but for various reasons we had a
    team that decided to take Tux out of the picture. I think the problem
    was more likely lack of knowledge and lack of time to do analysis on
    the particular problems. Another combination of solutions was used.

    So, any comments I made which might have implied that Tux/Tux2 made things
    worse have no substantiated data to prove that and it is quite possible
    that there is no such problem. Also, this was run nearly a year ago and
    the state of Tux/Tux2 might have been a bit different at the time.
