title: Symfony2 Slow Initialization Time
body: <p>I have Symfony2 running on an Ubuntu Server 12.04 (64-bit) VM (VirtualBox).  The host is a MacBook pro.  For some reason I am getting really long request times in development mode (app_dev.php).  I know its slower in dev mode, but I'm talking 5-7 seconds per request (sometimes even slower).  On my Mac I get request times of 200ms or so in development mode.</p>
  
  <p>After looking at my timeline in the Symfony2 profiler, I noticed that ~95% of the request time is "initialization time".  What is this?  What are some reasons it could be so slow?</p>
  
  <p>This issue only applies to Symfony2 in dev mode, not any other sites I'm running on the VM, and not even to Symfony2 in production mode.</p>
  
  <p>I saw this (http://stackoverflow.com/questions/11162429/whats-included-in-the-initialization-time-in-the-symfony2-web-profiler), but it doesn't seem to answer my questions.</p>
