title: superslow swipe reaction - how to speed up sencha touch / phonegap
body: <p>i have a simple sencha touch app in mvc style with one view in the viewport: the main view.  another panel is popping up as modal floating window when you swipe a finger over the main view. this panel lies inside a variable of the main view script. 
  my problem: on iOs devices (via phonegap) the popup appears really late - like 2-4 seconds after the swipe happend.
  is this normal or are there ways to speed up sencha touch/phonegap, maybe by preloading the popup, preopening it and making it innvisible...?</p>
  
  <p>thnx!</p>
