title: can I detect slow device in phonegap
body: <p>I'm making a phonegap application that has a page slide function. It works fine on fast devices, but on slow devices it's laggy and gives users a bad experience, so I have made a version that's not as pretty, but it works better on slow devices.</p>
  
  <p>Now my problem is, that I can't find a way to detect whether or not the device is slow. I can probably check the api version on android, but old samsungs are running 4.2.2, so it wont do the trick.</p>
  
  <p>So how can I detect a slow device in phonegap?</p>
  
  <p>cheers</p>
