title: Lighthouse & pagespeed insights performance score is inconsistent
body: <p>I have a simple html file below and when i run an lighthouse audit, the performance score is different each time.  I'm using chrome, no other programs running in the background.  I sometimes get 99, then other times 65, then other times 77.</p>
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
  test
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  <p>This is the same issue i have with Google pagespeed insights.  My webpage loads instantly but i can't even get over 15 score in pagespeed insights, highest is 55.  How do i even debug, if there is no consistency?  How do i solve?</p>
