I just learned via #jack that smp support only applies when you use JACK
with parallel clients. Bit cryptic but better described here:
http://www.grame.fr/~letz/jackdmp.html
"Jackdmp current implementation allows explicit parallel clients in a
graph to be processed on several available CPU at the same time. A
typical case is:
* in == > A ==> C ==> out and in == > B ==> C ==> out
A and B depend of the same input (the "in" driver in this case) and can
be activated on 2 processors, C waits for A and B outputs. "
So afaik if you use Jack2 with a single client like Yoshimi it doesn't
take advantage of its smp support, hence it shouldn't make a difference
whether you use Jack1, Jack2 or tschack.
Hopefully I didn't get this wrong ;)
Btw, I'm working on a tschack package for Ubuntu 10.04, almost done :)
Best,
Jeremy
