looking through the output of dmesg or /var/log/syslog should show if the
cpu has hyperthreading and how many cores there are. Hyperthreading should
not be a problem down to running jack with -p64, but it does make a
difference going lower... it may help make -p64 more stable too. If you
have hyperthreading this can be turned off by disabling every second cpu.
That is if you have a single core system with hyperthread, you will have
cpus 0 and 1, disable cpu 1 as it is really just the hyperthread on the
same cpu.

Just to be sure... you are not by chance using a wireless networking IF? I
have one that gives xruns even at -p1024 :P
