I unwittingly turned off all forms of doctrine cacheing on my Symfony2 application last weekend. After three days of dissatisfied users, frantic but fruitless optimisations, and banging of heads off desks, I stumbled across this article. I checked my config and reactivated these caches - really not expecting much. I was shocked at how dramatic and complete the improvement was - much more so than this article suggests. I went from a virtually unusable server consistently at loads upwards of 30, to one that flies with a steady load well below 1. An improvement of several 1000%. Magical. Thanks!
