FWIW, wanted to share some impressive performance I managed to pull off
earlier today from my new toy:

RECIPE:
1 Macbook Pro
1 Ubuntu Dapper (vanilla 2.6.15-26 kernel)
1 adjustment to rtlimits (total of 2 lines)
1 fglrx driver
1 Xgl with all eye-candy you can get
1 JACK + Qjackctl
1 32 x 3 buffer size

Mix it up. Run in realtime.

RESULT: xrun-free 2ms latency on a crummy built-in soundcard (2 in, 6 out)
plus all the eye-candy goodness you can possibly dream of at approx. 14%
CPU. ;-)
