Using the page-analyzer tool to optimize loading of my app

[alex9311]

Hey all,

I recently finished an ext app and it is loading really slowly to the browser. I'm trying to use the ext page-analyzer tool but I don't really understand how to interpret the information the page is giving me.

My app is basically a viewport which contains a grid (blazegrid) and a panel (maildetailmasterone). The panel contains two sub-panels (maildetailone and maildetailtwo).

To me, it looks like maildetailmasterone is being layed out several times (in run 2,3 and 4) and the viewport is taking a really long time to get setup. Am I analyzing this right? If so, are there ways to fix these issues? I'm working in MVC
