title: google PageSpeed Insights inconsistent result
body: <p>When I test facebook with google PageSpeed Insights, I am getting highly inconsistent results. It gives different result for <a href="http://facebook.com" rel="nofollow">http://facebook.com</a>, <a href="https://facebook.com" rel="nofollow">https://facebook.com</a>, www.facebook.com, ... and also sometimes it is showing different result at different time for the exact same url. (The results are shown very poor most of the time and facebook it is)</p>
  
  <p>Why is this happening?. Is it facebook behaving differently at different times?.</p>
