    Slow rendering of Ext JS

    I have read many articles about how slow the rendering speed is on Ext JS. I accept with a javascript library of this sort their will be some time delay, but even with relatively lightweight screens on the development server we are waiting 4-8 seconds for a refresh, on the web server its even worse.

    Please are their any techniques or tips regarding how to increase the speed of the Ext JS library, like cache settings, compression software anything. Even with XRender-ing controls the base library rendering is not fast enough.

    Any help or suggestions at this stage would be greatly appreciated.
