Jock,

My network rendering for large images shows the expected speed increase when considering the relative performance of the computers in the network. I don't have the numbers for you right this minute, but I do remember specifically benchmarking the network rendering in order to verify that it was working. If you watch it, though, it sure does seem like it's erratic, and the pixels/sec numbers don't seem to correspond to the overall speed.

Of course, network rendering does not help flames.
