title: Phonegap low performance issue
body: <p>I built an android app using PhoneGap and JqueryMobile framework containing several html and js pages.</p>
  
  <p>the first loading time is very high ( 5-10 seconds later vs native apps) and page navigation is too slow.</p>
  
  <p>Navigation from one screen to another taking lot of time.</p>
  
  <p>Are there any hints/howtos/tricks to increase speed? It's really unusable for an often used app.</p>
  
  <p>An other issue is too app's memory usage ( around 50mb for a simple application)</p>
  
  <p>All tricks and hints are welcome.</p>
