[LAU] tracking down xruns

hey list, I've been struggling for the past couple of weeks trying to get my netbook to perform well as a lightweight music workstation (mostly synth work, light daw stuff). I'm getting many, many xruns, clients getting kicked, etc. something is clearly not right. how do I begin tracking down the source of xruns? I have an -rt kernel, a usb sound card using -p256 -n3, running fluxbox with only wicd running to manage my network. point is, I've tried the hunt-and-peck method and (surprise) it hasn't done any good. how can I go about finding out what exactly is tripping jack up, and what I can do to stop it? (PS - I've said it before: maybe I'm expecting too much of a netbook. could that be it?) -- Josh Lawrence http://www.hardbop200.com
