You will always get xruns when you connect or disconnect a client. It's considered normal and JACK does not make any effort to prevent this. Same way you get a click when you plug something into a mixing console. A more useful measure would be the lowest latency settings + kernel combination that does not produce xruns during normal playback/capture. Lee
