Can someone explain the behavior of the Fast Tree Item in GXT 2.0 and how it differentiates from the standard tree items? I didn't see much in the Javadoc, and from looking at the GXT 2.0 demo explorer didn't pull out much (other than it is fast for 500 items)

It's a faster rendering version of the tree item widget. To accomplish this, the fancy CSS mouse-overs and rounded borders were removed since they added to the rendering time. I think the DOM element structure was also collapsed for the fast tree.

Excatly. The dom structure was minimized and it uses bulk rendering. But because of the minimized dom structure it doesnt support the rounded corners etc.
