title: How to enable cache in dev mode?
body: <p>I'm working on a heavy-load Symfony optimization, trying out template cache, doctrine cache, etc. But unless I'm wrong, those caches are disabled in dev, so it's hard to evaluate the effect of those optimizations.</p>
  
  <p>Is there a way to enable caching in dev mode, so I can the application optimization results while keeping the debug bar?</p>
