title: Multiple files on CDN vs. one file locally
body: <p>My website uses about 10 third party javascript libraries like jQuery, jQuery UI, prefixfree, a few jQuery plugins and also my own javascript code. Currently I pull the external libraries from CDNs like Google CDN and cloudflare. I was wondering what is a better approach:</p>
  
  <ol>
  <li>Pulling the external libraries from CDNs (like I do today).</li>
  <li>Combining all the files to a single js and a single css file and storing them locally.</li>
  </ol>
  
  <p>Any opinions are welcome as long as they are explained.
  Thanks :)</p>
