It seems that ExtJS creates large numbers of DOM objects (mostly

's) around items that it creates, particularly formsets. With a large program, this can be so dramatic that the page-render time is slowed substantially just by the browser trying to figure out what the layout of the page should be, with these huge piles of objects.

I'm not sure what the right solution to this is. Doesn't ExtJS have a grid control of some sort?; maybe that control uses a simpler layout mechanism? Since all we want is basically a giant table.
