Alldrupalthemes.com did a performance comparision between Joomla 1.5 & Drupal 6.1.

These numbers are interesting and I bet the study pulls in a lot of visitors for All Drupal Themes. Not only are Drupal and Joomla users interested in these type of posts, but so are potential users shopping around the first time for a CMS. As always, you should judge a CMS by what it does for you and not what it does for others.
