Daniel,
One sort of urban legend that's out there in the Linux audio
community has to do with the value of a dual vs. single processor
systems and how much they can help in this area.
The argument seems to go that on a DP machine one processor will handle the GUI/OS/drivers and the second processor will handle the audio application. However, no one (that I know of anyway) has really measured this quantitatively and shown it to be true. (It might be to subjective anyway...) Any thoughts?
My concern has generally been that every SMP machine I've looked at (admittedly not that many) seems to be a generation behind in chipsets and memory technology which goes against the goal. If I agree to pay more money for a second processor I'd at least like the rest of the machine to be equivalent technology.
I've never used a Linux SMP machine, so I have no idea how one tells the system to run a certain app on a certain processor, but I can see it should be possible I suppose.
Thanks for any thoughts you might have.
The Australian Partnership for Advanced Computing has researched that little dilemma:

The article says they now have 150 clustered single-processor Dell boxes and didn't go with SMP boxes for price/performance reasons.
