My Platform Is Faster Than Yours (or maybe not)

Do you find your self asking "Why is my site so slow and should I just migrate to platform X since everyone I talk to says it's so much faster?" Often it is far more difficult and costly to move to a new platform, and much easier to fix the site you currently have. We are going to benchmark a number of the most popular Open Source PHP Web Content Management Systems and see which one comes out on top.

This session will present performance metrics from load tests performed on:
Drupal 6, PressFlow 6, Acquia Drupal 1.2, Drupal 7, WordPress 3, Joomla 1.5, eZ Publish 4

NorthPoint has many years of experience building very high traffic sites on each of these platforms (not Drupal 7 yet) and understand where each requires a bit of tuning to handle real world spikes of 2 Million pageviews per hour or more. We will be testing each of these platforms in their "out of the box" state, with basic caching applied to give realistic results across the board. Testing results will display the following under different scales of load, as well as analysis of total page weight of the homepage and a content page.
