If you create a sample Sencha Touch 2.3 app using sencha app generate... and package it with Cordova, you will see that it takes about 4 seconds to launch the app and show the main view. If this basic skeleton app takes this long, then actual apps that have many more views, controllers, stores etc will take much longer (6-8+ seconds).
Is there any way to speed up the launch? For reference, lets take the example of the sencha started app itself. It takes 4 seconds now. So how do we improve the performance so that it takes 1 or less than 1 second to launch?
