"Drupal can't scale" has almost reached urban legend status. Talk to anyone not familiar with Drupal and you're certain to hear this criticism of Drupal. WorkHabit has scaled sites to handle the traffic from millions of active users and we'll explain strategies for scaling Drupal. This session will show you how to make Drupal scale on everything from shared hosting to large-scale clusters. You'll learn things you can do immediately to improve performance, reduce your server load, and increase the number of users your site can support. Whether you're a new site administrators or an old Drupal hack, you're sure to pick up some useful tips from this session. We'll talk about caching, tuning your code and database, and how to make Drupal handle billions of pageviews per month. This is an interactive session and asking questions during the presentation is encouraged.
