You can change that during compile time. Here is a good write-up on frame rates: http://ajax.sys-con.com/read/303778.htm <http://ajax.sys-con.com/read/303778.htm> Question: Are the 300 plus UI elements the checkboxes, labels, etc.that you have in the application? They seem to be showing up almost right away, at least for the first tab. If you are writing your application code logically you can employ a lazy loading scheme whereby data is not loaded (including data binding) until it is really needed. Again, I haven't looked at your code, so I'm not sure how much data you are pulling in. One thing you could do is temporarily comment out any code that actually loads data and then see how your application behaves. If this eliminates the delay, you can start enabling the data loading mechanism one by one to see where the delay is introduced.
