This is a great article on tuning Drupal for performance following Yahoo's Best Practices for Speeding Up Your Web Site. It takes you through each rule and shows which ones are covered in Drupal and, when they're not, how to find a work-around.

Traditionally, the way to improve the performance of a Drupal site is to enable the page-level cache. While this may work well with a site that only has anonymous users, it will not be used at all for authenticated users. Drupal just can't tell whether the page contains sensitive or personalised content that should not be shared between users.
