I found a very confusing behaviour some days ago. I was trying the limits
of my jackd system and got as far as -R -n 2 -p 16. Just jackd running, no
ardour nor any other jackd client.
Then I just moved mouse around my kde (focus follows mouse was on) and
witnessed xruns during the focus changes.
The confusing part was that after I reniced most of my running processes
to lowest (19) priority, I got fewer xruns when moving mouse across kde.
I have lowlatency and pre-emptive 2.4.20, M-Audio Audiophile 2496 at irq 9
(nothing at irq 8 & 10), ATI card at irq 11, Athlon 1700+
I thought that renicing shouldn't affect since jackd is running -R
