Yes, we could use Tux, yes we'd get better results. But that's not the point ;-) Of course. I just don't want propaganda being spread that using Tux means you lose any sort of web server functionality whatsoever.
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. gerrit
