Eight physical cores.

No, it should not, as you explained! :-) <br>

So I assume you think the following:

Best to not assume. :-)<br>

What is happening right now, is I have seven synth+filter chains,
all run through the single JACK server, all feeding eventually into
the one sound card. I have more than ample CPU to run them all, but
as you and others have explained, one JACK server is reaching its
limits to handle them all because of the limits of the synchronous
nature of everything. So what I intend to do, is to run all of the
chains independently, asynchronously, on their own JACK servers, and
then combine them all into a separate final which will connect to
the sound card. This is being done already with as many
motherboards as desired, but I would like to do it within one very
powerful box.<br>
