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.
