I am using Ext Js-4.0.2 for my project and all my pages are static html pages.
I observe that, the html pages load very slowly, in the browser like, IE 7, IE 8 and Firefox 3.8.
I have not tested in other browsers.
I have kept all the folder structures as it is from the downloaded sorce library.
Only modified my required things.
As per EXT-Js 4 coding structure, inside the JS files, I call all the Ext.require() first and then the onReady() function.
I am not using any remote data load also for my grid or form.
Please let me know, how can I improve the speed?
