It's worth having a small one -- say 32MB -- just to make the initial usage faster. It helps a lot with fresh writes at the beginning. Once you've been using it for a while, you might find that it's worth turning off, but it's easy to just remove from the config (just don't put it back). Only power-of-two sizes are used -- 32MB, 64MB, etc. Russ
