Not for the faint of heart but I have Drupal that boots without SQL using memcached. It's fast. Very. If you have a focused site, you can gain from running a code coverage script and moving everything to conditional includes that's not used on the focus-pages. You can easily get several hundreds of requests from one small machine.
