What do you mean?  What are the symptoms?  Do you get xruns, or
something else?  What period size are you using?

You can try Rui's jack_test4 suite to get an objective benchmark of your
systems audio performance.  You should be able to increase the number of
clients until the DSP load or CPU load get near 100%.  How many clients
can you run jack_test4 with before your system falls over?

I have a 600Mhz C3 that can run about 7 jack_test4 clients before it

I think jack_test4 is included in JACK CVS, or there is a plan to
include it.  See the jackit-devel archives for details.
