Memcached, a high-performance memory caching system is the tool for the solution. This post is an answer to the question of how to integrate memcached and drupal to speed up your site.Read more >>

To run your drupal site on nginx, the lightweight web server, you will need a custom conf file to make nginx working with php. If you want to enable drupal's clean url function ( maybe you should because a clean url is both more user-friendly and Search Engine friendly ), you will need a additional nginx rewrite rule.
