title: How to measure rendering time in Chrome 1000 times?
body: <p>I am working on a proof of concept and I need to measure the rendering time  of a simple website (just a HTML document and one CSS file) 1000 times in a browser. Is there a simple and straightforward tool for this?</p>
  
  <p>I know there are some highly complicated tools with an enormous learning curve, but I don't have the whole week to tinker with it. I don't need anything else just the rendering time, exactly as Chrome's Performance tool displays it in milliseconds, then calculate an average.</p>
  
  <p>If someone could tell me how to find the total rendering time of the page in the (quite enormous) JSON output of the Performance tool, I'd be happy with that. I can have a macro recorder clicking the Refresh button all night. Though I guess there's a way to get it done from the command prompt - any advice is appreciated on that too!</p>
