title: Chrome is slow to load first AJAX response
body: <p>I am building an application using React and Flux. Clicking in a list of items initiates an action which then starts (via an effect) an AJAX request using <code>axios</code> (though I have tried <code>superagent-bluebird-promise</code> with the same results).</p>
  
  <p>The issue is that using Google Chrome, when first making this request, there is a delay of approximately two seconds between clicking the item in the list and the AJAX request being initiated. Subsequent clicks instantly start loading the request.</p>
  
  <p>Using Firefox, all requests are instantaneous.</p>
  
  <p>Edit: I have tested on two Ubuntu PCs, and can replicate the same symptoms. I can also replicate the symptoms on my Android, with a bigger delay (about 4 seconds).</p>
  
  <p>Here is a screenshot of a profile made under Chrome:</p>

  <p>Is this a bug with Chrome, or what?</p>
