Actually after a reboot and some more tweakings, things have been
running without a xrun for an hour now, even with periods/buffer=2.
So finally, i'll stay with planet ccrma ;)

Argh, actually i still have audible xruns. And i don't think i'd be
able to play correctly with a higher latency anyway...
Think i'll have to get back to ubuntu studio ... :(

Okay, i had forgot to turn off the system "bips" and esd (it reduced
the number of xruns)
And yep with -n3 i 've got even less xruns and it seems they're not
audible.
I don't know if the latency is low enough though, i'll test this
evening with my drum pads.
Thanks everyone , it's really great to get so much help so quickly.

.jackdrc:
/usr/bin/jackd -R -P70 -t1000 -u -dalsa -r44100 -p64 -n2 -D -Chw:0,1
-Phw:0,0 -S -i2 -o2
USB-Devices often perform much better with -n3. Furthermore I would try
to eliminate any flag, that is not absolutely needed such as:
/usr/bin/jackd -R -dhw:1 -dalsa -r44100 -p64 -n3
BTW: this would compute to around 4 ms latency - is that good enough for
you?
