If you are running under Linux.. load it up with RAM... the OS will hold
any recent disk reads in cache... particularly a simple html document
with a few locally held images. I've watched disk access on some of my
boxes, some sites serving 1gig per day, and the disk just barely blips
along... most being served from cache. Linux rules!
