title: Using Chrome with `--headless` switch to measure user page load times
body: <p>I'm trying to improve the performances of my web server and would like to get an accurate measure on how long it takes the user to load the page. The way I imagined this would be to simulate concurrent requests from users and track how page load times change as I fine-tune various settings to get optimal results.</p>
  
  <p>I'd like to use the latest snapshot of Chromium with the <code>--headless</code> switch to measure how long it would take the user to load the page, but since this is a relatively new feature and I'm not familar with <a href="http://peter.sh/experiments/chromium-command-line-switches/" rel="noreferrer">all the possible switches</a>, I'd appreciate if someone can share what they would run to get accurate results.</p>
  
  <p>The only limitation I have is that I can't inject scripts or modify the response content in some other way that would be helpful for such a test.</p>
