your problem screams after better hardware. kernel tweaking will bring you an unstable system, grey hair, insomnia, smelling underwear and if you are lucky 1-2% gain in performance. no one will be able to help you, if something goes wrong. if you got a high interrupt load, take better nics. if you got no cpu left, take a better one. obviously, the wrap boxes aren't built for that kind of performance. you can make a racing lawnmower out of a lawnmower by tinkering and losing you warranty, but it'll still be a lawnmower. --knitti --knitti
