title: Chrome update slowed Ajax/Angular Network rendering and loading
body: <p>About two weeks ago, a Chrome update crippled users of my angular app. I load a lot of data but the entire single page application loaded in <code>&lt; 4</code> seconds but every single user went to <code>&gt; 40</code> seconds after updating Chrome 2 weeks ago. I did not experience the problem, but when I upgraded <strong>Chrome</strong> to <code>64.0.3282.167</code> from <code>63.0.3239.132</code>, the problem also began for me. </p>
  
  <p>Somewhere between Chrome <code>63.0.3239.132</code> and <code>64.0.3282.167</code>, there was a change that basically slowed my Angular app to a crawl. It affects loading and rendering across the board and made the entire app almost unusable. I've been looking for the issue for a few days with no joy. </p>
  
  <p>Does anyone have any insight or recommendation on what could cause such a performance degradation?</p>
  
  <p>Here is a screenshot of my network tab. All of this used to be very fast before the Chrome update and now it just crawls.</p>

  <p>If I set:</p>
  
  <p><code>httpProvider.useApplyAsync(true)</code>, it alleviates the problem but my application is huge and this causes a lot of erratic behavior in a 5 year old application. </p>
