Ram woes
Harold,
I can't answer your question about the additional ram substantially decreasing
your rendering time. I suggest that you optimize your hard drive each time you
render, so that you have contiguous space for that large swap file. Is the
final output size rendered at full resolution, if so, you might want to do a
test sample with the output at a smaller file size. Some of the RIP software at
your local image houses do a real good job of pixel sampling and you can get
away with a much smaller file.
