There's a noticeable spike in performance at regular intervals of about every 15 frames for me. I'm testing using the sender scene included in the demo.
Here's a snapshot of the profiler with four senders.

Which becomes much more apparent with eight senders. I'd expect a general drop in framerate, but this is more of a stuttering effect.
