IIRC Jack's DSP load measurement indicates peak load over the
recent history. A client that generates a very uneven load (e.g.
doing big FFTs every Nth cycle) can easily make it indicate
much more than the average CPU load. Of course clients doing
that are just badly implemented, but they do exist.
The complexity of the graph doesn't look like an issue to
me, I'm routinely running such things without any problem.
