<h3 id="n:1.1.2.">1.1.2. Mixer Strips</h3>
<h3 id="n:1.1.2.">1.1.2. Mixer Groups</h3>
<p>
Groups serve several purposes. Firstly, they allow for some organization of strips. Groups also allow parallel relationships of mixer strips to be made explicit. This has important performance implications in JACK2. Non Mixer supports an unlimited number of groups, each of which can contain an unlimited number of mixer strips.
</p>
<h4 id="n:1.1.2.1.">1.1.2.1. How to Choose Groupings</h4>
<p>
All strips in a group should be completely parallel with no feedback loop connections. A typical group might be named 'Input' and contain all input strips (strips that accept input from Non Timeline and have outputs all connecting to some master bus).
</p>
<p>
To put it another way, if you have 100 inputs strips with identical output configurations (e.g. stereo or B-Format), that all connect to a master bus, then you have a candidate for a group.
</p>
<h4 id="n:1.1.2.2.">1.1.2.2. Considering JACK Overhead</h4>
<p>
JACK provides immense flexibility. But, as in most situations, that flexibility comes with a cost. In JACK the cost is a context switch per client. This applies <i>even for many clients which belong to the same process</i>, as in Non Mixer. Various factors go into determining the price of a context switch on any given system. It's not very expensive, but it does add up. It becomes problematic in sessions involving many clients (think 100s), each of which having a small DSP load (often smaller than the cost of JACK's context context switch). JACK <b>could</b> be smart enough to recognize that some clients belong to the same process and could be executed serially without requiring a context switch, but at the time of writing neither JACK1 nor JACK2's scheduling is that smart.
</p>
<p>
If you're mixing a normal song (couple of dozen tracks) at low latency, this overhead will probably account for less than 1% of the total DSP load. If you're mixing an entire orchestra at ultra-low latency, then it might account for a quarter or more of the total DSP load.
</p>
<p>
Groups mitigate this cost by reducing the number of JACK clients required for a mix. Strips in a group will execute serially without context switches or thread synchronization--reducing the total JACK overhead. However, if you have several groups, then they may all by run in parallel by JACK2.
</p>
<p>
<p>
To illustrate this point here are some figures from an actual song session including the whole Non suite plus a sampler, a synth and an ambisonics convolution reverb with a total of 13 strips in 4 groups in different configurations on the same system.
</p>
<p>
JACK's DSP load figures are interpreted thus: if at a 2.7ms software latency setting the average time a proces cycle takes to complete is 2.7ms, then the DSP load is 100%. The usable ceiling on DSP load is 80%. This is true for both JACK1 and JACK2. The difference is that JACK2 may use all available CPU cores to execute the graph \(if there are enough clients in parallel signal flow\).

As you can see, for multiprocessor systems, JACK2 clearly has an advantage even without grouping.
</p>
<p>
Of course, results will vary depending on the system and the mix. On the dual core system, performance actually degraded with JACK2 when using groups--this is because the number of parallel flows that JACK2 detected was reduced and the second core was being under utilized. Similarly, the performance of the 8-core AMD system doesn't seem that great even in the ungrouped mode--this is because the DSP load of each individual client is around the same as the cost of the context switching. It's a wash either way (if each strip had more or more complex modules on it, then the ungrouped mode would probably perform better). Since JACK1 cannot take advantage of more than 1 CPU core, there is no benefit to parallelism and grouped mode always outperforms ungrouped mode.
</p>
<p>
So, for maximum capacity the combination of a multicore CPU with JACK2 and mixer groups is best.

JACK provides immense flexibility. But, as in most situations, that

A mixer which uses a single JACK client (which is basically the way
everything other than Non Mixer has been designed) is not a viable
solution by this author's definition, because such a mixer cannot be
from/to any other JACK clients without introducing an extra period
of latency.
To illustrate this point here are some figures from an actual song

ambisonics convolution reverb with a total of 13 strips in 4 groups
