title: Measure full page size in Chrome DevTools
body: <p>I've been googling for some time but haven't found any clear solution for this.</p>
  <p>I want to measure full webpage weight / size (all document + scripts + fonts + styles etc.). I know the network tab in the devtools has size/content - but I want to have it summed (and not sum it every time).</p>
  <p>I've been looking for chrome.devtools.* API but haven't found anything straight-forward.</p>
  <p>Do you have some ideas how to achieve that?</p>
