title: How do I track site loading and tag latency over time using chrome on the server?
body: <p>With an increasing mobile user base I would like to be able to gauge a baseline for site performance. Typically I can do this using chrome dev tools, checking when DOMContentLoaded finishes, and checking all my javascript tags to make sure they're in acceptable threshholds. How would I go about automating this so I can create performance dashboards?</p>
  
  <p>Maybe phantomjs, selenium can do this? What headless chrome implementation could I use to achieve this.</p>
