I thought that _ought_ to be the case but I was suspicious because of the /proc/sys/kernel/lowlatency thing and also because I get very noticeable audio dropouts when I do things like task-switch. jackd doesn't report xruns though. Am I correct in thinking that if I start jackd as root I don't need to use -R or jackstart or anything to get good performance? At the moment I think I'm using jackd -d alsa -d hw:0 -p 512 (although that's in a script on my other PC so I might be mis-remembering). Cheers.
