Greetings, everyone.  Since I am using 85% of JACK DSP in my primary
production box, while using 14% of the CPU and 1/8 of the RAM according
to htop, it appears that I need to develop a way to move forward :-)

14% of what? One physical core? One virtual core? All cores?
Eight physical cores. 
I would like to use the power of my box to do the same internally.

Jack should be doing this already in a single instance.
No, it should not, as you explained! :-)  
From what I just read:

* You noticed, that there is a high DSP load for JACK
* You noticed, that there is a low CPU load on you box, which has most
likely multiple physical cores?

So I assume you think the following:
Ok, my Hardware still has free CPU resources, and since JACK is supposed
to be a smart thing, it should be able to utilize all of my CPU cores.
Best to not assume. :-)

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.
