So here they are. This machine is a P4 2.80C@3.366GHz, HT enabled on a
Asus P4P800 mobo, Intel 82801EB onboard sound device (snd-intel8x0).

2.6.9smp RT-V0.6.9smp
------------ ------------
XRUN Rate . . . . . . . . . : 0 0 /hour
Delay Rate (>spare time) . . : 0 0 /hour
Delay Rate (>1000 usecs) . . : 0 0 /hour
Delay Maximum . . . . . . . . : 346 166 usecs
Cycle Maximum . . . . . . . . : 986 1028 usecs
Average DSP Load. . . . . . . : 25.0 25.7 %
Average Interrupt Rate . . . : 1717 1718 /sec
Average Context-Switch Rate . : 10082 15793 /sec

As you can see, the results here aren't so disparate as on my UP laptop.

I guess that I can stress this out and lower the period size on jackd -R,
to -p64. And even increase the workload with more client instances (from 9
to 18 ?) to let the RT show it's potential, if that makes sense at all.

Bye now.
