title: Phantomjs works but is very slow
body: <p>I am trying to take a screenshot of a webpage with PhantomJS. Specifically, I am using the example of capturing <code>espn.com</code> from <a href="http://skookum.com/blog/dynamic-screenshots-on-the-server-with-phantomjs/" rel="noreferrer">this</a> example. My code looks like this:</p>
  <pre><code>var page = new WebPage(); 
      page.open('http://www.espn.com', function (status) {
      page.render('fb.png');
      phantom.exit();
  });
  </code></pre>
  <p>I then go to my PhantomJS directory with either my terminal or command prompt and run:</p>
  <pre><code>phantomjs shotty.js
  </code></pre>
  <p>Everything runs great, however it takes 6-8 seconds to complete the output image. Is that normal? Is there a faster way to accomplish this so that it completes in a second or less?</p>
  <p>I am using CentOS and Windows 7. Both boxes have 8GB of RAM, 3.2 GHz CPU, and I'm getting 22Mbp/s down and 1Mbp/s up on speedtest.net</p>
