I recently put an app on my iPhone 4, and I'm appalled at how much slower it is on the device as compared to the simulator.

There are two things, in particular, that are slow.

First, the pages have a delay before getting rendered. All they have are some labels and textFields. I'm using JS includes throughout, so I wonder if that's an issue.

//Window 1
var win1 = Ti.UI.createWindow({  
   title:'Flight Plan',
   backgroundImage:'images/app-background.png',
   barColor:'#000',
   url:'includes/window1.js',
   translucent:true
});

The second thing that's slow is my scroll views. I'm assembling them like this inside window1.js:

var win1 = Ti.UI.currentWindow;

var scrollView1 = Ti.UI.createScrollView({ 
   contentWidth:'auto', 
   contentHeight:'auto', 
   top:0, 
   showVerticalScrollIndicator:true, 
   showHorizontalScrollIndicator:true 
});

var view1 = Ti.UI.createView({ 
   left:0, 
   right:0, 
   height:'auto', 
   top:0
});

scrollView1.add(view1);
win1.add(scrollView1);

Any ideas on what I might be doing wrong? Any ideas on how I can discover what's causing the poor performance?

Thanks!
