In addition to the great advice by Achim and Chris, I'd suggest that in some borderline cases, where images are being filtered with Core Image and rendered with a Billboard, that a modest improvement in performance can result from enabling the "Native Core Image Rendering" setting on the Billboard, despite the warning about possibly degrading performance. Test for your machine of course.
I've also, rarely, found some instances where "rasterizing" an output image at a particular stage in an image chain, by passing the output to a Billboard that's inside of a Render In Image patch (with a Clear at Layer1), and using the output of the Render In Image can yield a performance improvement, depending on various patches in the composition.
