He did change to lighttpd according to the first post, but it loads slowly the first time around. If its loading slow, I suggest you take a peek at the CPU usage, maybe thats why its taking quite a bit to process and then it processes much faster the second time around cause its making use cache. But yes, I definetly agree you should do some Apache + MySQL Optimization base on your usage and specs.
