title: iOS8 Webview performance still heavily slower than mobile Safari
body: <p>I'm developing a PhoneGap HTML5 app, which is doing some image manipulation.</p>
  
  <p>What I see is that the same script (<a href="http://fornace.io/jstests/gogh.html" rel="nofollow">http://fornace.io/jstests/gogh.html</a>) is taking roughly 10x more time to execute inside Phonegap than in mobile Safari (from 5 seconds to about 45).</p>
  
  <p>Since we all understood that iOS8 Webkit finally <a href="http://9to5mac.com/2014/06/03/ios-8-webkit-changes-finally-allow-all-apps-to-have-the-same-performance-as-safari/" rel="nofollow">allowed all the apps to use the same Nitro engine as Safari</a>, I wonder if someone can explain how this huge difference is still there, and if there's a workaround.</p>
