title: Images loading slowly (15+ seconds) in development?
body: <p>In my config/environment/development.rb file, I found that setting:</p>
  
  <pre><code>config.assets.debug = false  # Debug mode disables concatenation and preprocessing of assets.
  </code></pre>
  
  <p>Considerably sped up my development server when using a large number of javascript and css files.</p>
  
  <p>The only problem is that when loading images, the development server takes a long time to load each image.  The server output is as follows:</p>

  <p>Is there anyway to speed up the loading of images in development mode?</p>
