Hello Watit ,

We guess you have set the IsContentPreserved property to True. This makes the RadTabItem's Content to be saved in memory and once the Tabs have been loaded, switching between them is faster operation that their initial load. On the other hand, it is somehow expected that your tabs need some time to load initially - you have several Pane and Chart controls which need their time.

Hello Watit ,

 We believe this performance is expected due to the large number of controls you use in the TabItem's Content and their. You can compare your app to this demo. Large controls just need their time to load themselves and to load their data.

Hi Watit,

 I think scenarios like (1) and (2) cannot be achieved. The only thing that you can do (which determines how the tabs are loaded) is playing with the IsContentPreserved property. However, we still think that the performance of your application is expected, having in mind the big number of controls that you use in each tab. For example, once loaded, your tabs' selection change is faster than the tabs' selection change in this application.
