    Question Improving Form Rendering Perfformance

    Hi All,

    I have a rather large/complex form that is rendering inside of a tabbed interface, and the render time is rather slow (about 10-12 seconds). Any thoughts on how I can go about improving performance?

    https://fiddle.sencha.com/#view/editor&fiddle/2d0j

    Any insight would be greatly appreciated.

    Thanks in advance.

    You might take a look at this blog post, seems relevant to your scenario.

    Also, seeing if you can break down this form into smaller parts (i.e more like a wizard). Can you have the fieldsets default to "collapsed" and then you add the subsequent fields after an "expand".

    The usual way is to suspend the layouts. I am not sure about a bug in 6.5.3

    Ext.suspendLayouts();


    Ext.resumeLayouts();

    I think to suspend events with help as well.

    this.suspendEvents();
    this.resumeEvents();
