Drupal developers love their modules. However, Drupal doesn't always scale well out of the box with all the modules enabled. This session will be a look at what we have done to make sites scale and perform well even when the developers and customers go crazy. We will take a brief look at database tunes, multi-memcached, authcache, squid, and load balancing. We will touch on metrics gathering and measuring, finding the bottlenecks, and figuring out where you need to look.
