Yupp, I see. I get a 7 percent penalty compaired to
doing
the same just in one process.
right. now try it with 8 different processes, all of them touching
enough (different) data to invalidate a random selection of about 80%
of the cache. or better yet, just take our word for it that the cost
of the context switch is significant.
you also haven't addressed kernel scheduling issues; the context
switch doesn't happen till the kernel has decided what task is going
to run next. if it picks the wrong one, for whatever reason, then
you/we lose. right now, it picks the wrong one too often, even with
SCHED_FIFO+mlockall.

not talking about jack tasks, I'm talking about doing a simple
plug-in
task
inside a standalone program, the way the vst server works.
i don't understand how the vst server works. perhaps you can explain
it.
