But you are ignoreing the fact of how often images are called, even if cached. Theres quite a few images here that apache would not have to deal with serving. Since i left your hosting I've moved from my own hosting company to consulting for lots of bigboards now and have been doing fieldtests of differnt methods to improve website preformance under high usage loads. I'm currently looking into not only clustering but also in general spacing systems to do specific tasks and working on finding programs that better accomplish tasks. Apache is a decent program for processing php, but lighttpd is doing a much much better job serving static content (images etc) and I'll be testing how it does with php in the naer future. However there are already a few very large boards who've made this transition and its been wonderful.
