With dual opterons at the moment my load average (except for when compiling) is 0 - 0.1 but my electricity bill is significant so i'll be looking into something atom/nano based in the near future, especially when i can get a motherboard with CPU for less than 60 uk pounds. > > >> -- >> David Kelly N4HHE, dkelly@HiWAAY.net >> ======================================================================== >> Whom computers would destroy, they must first drive mad. >> > >
