Analyzing Ext JS Apps with Chrome Performance Tools

Have you even clicked a button or selected a row in a grid in an Ext JS application and it took a long time for the action to complete? And you scratch your head wondering why? Wouldn’t it be nice to be able to see what is happening in the browser with your application once you clicked, and be able to see all the functions that are called and, more importantly, how long those functions are taking? Then, you would be able to address the performance issue. Well, fortunately, that’s exactly what you can see with the chrome developer tools performance panel. In this webinar, we will take a look at how to use the performance panel to see what is being done in your application and, with this knowledge, you can apply the performance tool to your own application.
