rrrrrrriiiiiiiight. but the combo is not a traditional HTML item.
Please tell me you're not just using Ext JS for a single widget.

The truth, yes, I am developing the application that need to create multiple tab panel (20) all in parallel. And in each tab a form with at least 20 field. Then with the development team arrives at each form agreement to create a separate page, which loads its own library Ext. Truth works pretty fast

And what made you decide that loading two instances of Ext JS is a good idea?

We had two alternatives, first create all the components in a document object, that worked fine on my pc only, since it is powerful. The second is the aforementioned previous amount and the speed increased considerably.

Any suggestions?

I don't understand how you came to the conclusion that having 20 instances of Ext JS is faster.

The bad thing is that it creates many ext tag "div" and that eventually adds to the load to the browser, then divide the various interfaces in the browser iframe tag him like a new application and new resources allocated for that window. Test done you will be surprised.

Yeah, i still don't have a clue why you would think it's a good idea. :-\

i guess he is speaking about a new DOM-Tree in every iframe. i also had tests in the past to split huge parts of the dom tree into separate iframes to make manipulation of theses parts much faster. (at least in IE and without using extjs)
The downside ofcourse is, every iframe needs its own extjs and its harder to communicate between all these different iframe-dom-trees.

It works pretty well, but my question is different and I would not change the subject
