The data is on a separate partition, not a separate disk. It may be part of the problem, but it seems to me not a big part because the pattern of disk reads and dropouts only happens when I'm playing a session for the first time. The disk activity pattern is completely different when the machine is otherwise idling. And unless I go for a raid setup, the system would still have to read all the audio data off one disk. > Second, what FS are you using?

It's reading more than about 3 tracks that seems to cause the trouble. And if the output from top is anything to go by, it happens because disk reads cause the cpu to spend too much time waiting on io to prevent the audio buffers from emptying. I went through a patch a few weeks ago where I killed off every process that wasn't necessary, and the problem persisted. bye John
