You might want to consider LiteSpeed WebServer. They have a standard (free) version and a pro (paid) version that should perform much better than Apache and PHP. It should even perform better as Lighttpd and has the same rewriting-syntax as Apache. (In fact, it closely resembles Apache in terms of configuration).
