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).

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.
