On a side note, you can improve efficiency of a render farm when you have various CPU speeds involved by reducing the parsed out block size to the smallest possible. The default is the largest possible. If you set it to small (I think 16X16), the slow machine/s will only get hung up on small pieces and the faster machines will also have a chance to work on the hard parts of the image. Otherwise, the slow machines will get snagged on the tough parts or will be hanging on forever at the very end. If the slow machines have small pieces, it can optimize the render process. -Kix
