this particular test was done with an UP kernel. (although the testsystem indeed is an SMP box.) Generally i mention SMP explicitly. There are a couple of patches in the -RT tree to make RT scheduling better on SMP systems. with those fixes applied (i.e. under the -RT kernel), jackd/jack_test behaves better than on a single CPU. I didnt find any scheduling anomaly that wasnt caused by the kernel.
