I'm not familiar with that exact flowgraph, but nothing will "break down" in a CPU only flowgraph. Drag the ctrl port perf monitor block on to the flowgraph and look for the avg throughput counter for a block you care about. It'll give you items/sec. PS - the throttle block only gives you an approximate amount of throughput. The actual rate has nothing to do with whether the flowgraph works/breaks.
