The title is a little a canvasser but the purpose of this post is rather to get acquainted with 3 manners to make RIA and to compare them through a central component of an application: the grid.
I was thus used to recreate a simple screen containing a label, a button and a grid.
FLEX vs AJAX vs GWT on the Grid

They test GWT-Ext and ExtJS, which are quitely the same (GWT-Ext is a wrapper for ExtJS). They should test Ext GWT (full java implementation) where all javascript is generated and optimised by GWT.
Haven't you read the numerous posts on the Gxt or Ext GWT site where users have complained about how slow Ext GWT is compared to ExtJS -> GWT-Ext.
Performance wise, GWT-Ext is much faster than Ext GWT
No, I didn't see that. In my own experience of both products, I haven't seen the difference but I'd prefer objective benchmark than my own feelings.
GWT-Ext is slower not because of anything inherent in the way the GWT compiler works, but in the way Darren chose to construct widgets.
DOM calls = performance killer, so libraries with the fastest rendering are those that build the widgets by templating or strings, or cloning pre-cached nodes, and slamming them into the DOM with one operation like innerHTML or appendChild.
Just look at how Tree compares with FastTree in the GWT incubator.
Ray,
You mean Ext GWT aka MyGWT/GXT ..ExtJS has deliberately named their product similar to GWT-Ext confuse most users.
I agree with your assesment. The GXT implementation is poor, nothing to do with GWT
