If you have two graphs that are both using the same hardware device,
both graphs get pulled on from the same IO thread in series. Thus the
net effect of splitting one graph into two in terms of performance is
at best a wash and might even be slower due to any extra overhead.
You need to divide your work up between threads not just graphs.
You'll need to create and manage your own auxiliary work threads (and
their requisite synchronization requirements) to really take
advantage of multiple processors.

Very informative, thank you. Just one more question, about
audiographs: is it at all wise to create more than one (with evenly
balanced unit load), when multiple processors are available? Or
would this depend on the type of application at hand?
