I've often heard folks complain that Drupal doesn't scale well and has issues with performance. You'll hear people saying it isn't suited for large sites, or that it is bloated and too slow. A year ago, after a Drupal site failed abysmally under load (in less than 60 seconds) I was wondering if all of those statements and predictions were true.
Coders and system administrators who want to make their Drupal site perform like it is just running core. How to make busy sites run really well on even a single server.
