This thread became a really good lowlatency tutorial, great! :) I'm not sure what this IO_support thing is, but I guess it's in Jan's guide. There's just one other thing I thought I'd add that I didn't see mentioned anywhere. By default a linux system is running cron daemons that schedule the execution of different "things" at recurring intervals. Though I've never heard of anything happening with 20 minute intervals. That the spike occured 20 minutes into the the recording also speaks against it. It may be a good idea to turn them of though. /Robert
