What I've found helps, if you really need to squeeze that performance out of a server, is setting up a ram disk for your /var/ directory, or one small ramdisk for every small web page you are running. That running with lighttpd will probably be the fastest you can easily pull from a web-server. Also I try to never directly edit the ramdisk. I write changes to a git repo and write a small script to pull from the repo and directly write to the disk immediately.
