GWT Widget Performance and Optimization Solution

• Real world app optimization. The author had slow performance on a music app prototype.
• IE6 could take 4.5 seconds to render large track lists. Firefox 4 took 0.5 seconds
• He removed all listeners from all widgets and had only one on the tracks container.
• Each track carried a track id and position in json on a data-query attribute
• Next step was to remove widgets and build the html
• IE6 went down to .85 seconds,  Firefox 4 0.15
• Could probably used Cells, cells are lighter weight than widgets and they produce all the content as html.
