What > are the benefits that overweight the obvious performance degradation? I guess the main reason, at least for me, is that there is only one distro that properly supports LE ARM: Debian. It greatly simplifies management/administration of a higher number of devices, given the fact that Debian also supports other architectures (not just x86/64, sometimes PPC, like most distros do). Not always network performance is to most important factor. -- Tomasz Chmielewski http://wpkg.org
