--"As Steve mentioned, due to the fact that Bryce won't skip tiles this may make a render take longer or show only a small advantage (i.e. your fast machines won't start a new tile until the old machine has finished)."--

I may be misunderstanding what is being said here, but that's not the way it works when I am using Lightning.

I have a 1.7 Ghz and a 933 Mhz machine in the network. When the faster one is finished it starts the next tile whether the other is done or not. It does roughly two tiles for every one that the slower computer does.
