Improve performance in Urban Turtle

Edit Subject

Performance needs to significantly improve in Urban Turtle. Urban Turtle is generally slow--refereshing listgs, updating items, drag-n-drop, etc. While the functionality is generally robust, most users in my company find Urban Turtle annoyingly slow even to the point where they want to use the Visual Studio clients to access work items. Frequent comments from users like, "The name Urban Turtle is certainly appropriate" and "Why can't this be Urban Cheetah?" The normal TFS web access is much faster compared to Urban Turtle as well.
