Performance should be in the mind of every Drupal developer and site builder as they are building a site.

The best way to analyze and then tackle a site's performance issues is with data from the live production site. There are plenty of tools to help simulate that data, but nothing replaces good hard production data. Luckily Views Cache Bully has come to the rescue of distracted developers everywhere.
