I sometimes use a "huge" 6 core, 3GHz AMD machine and it lags when I open a Nautilus window under ubuntuÂ… This machine setup is pure ubuntu stock, it has power saving enabled. I don't care much but obviously there is room for tuning.
I would suggest disabling power management (in the bios) and see how the machine goes. On the linux kernel side you could try booting with option nohz=off and see if you get a different behavior. At application level you could try raising the priority of server processes, perhaps make them "real time" class (I don't think I've tried doing this with SBS; I would check if all processes launched by SBS are in the RT class.) Although your machine does not appear short of RAM you may want to experiment with vm.swappiness, too. In case you start seeing things that you like better, perhaps you'll want to compile your own kernel, changing kernel main loop frequency and task scheduler behavior. I'm no expert so I'll just point you to this conversation for inspiration: http://stackoverflow.com/questions/4956206/change-linux-kernel-timer (Of course I suppose you are not running a gazillion applications at the same time, with SBS sinking to swap. Check 'free' first.) ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=95551
