Tab page rendering time

Hello,

I am working on an windows application. In a form I have used a tab control, where the first tab page contains  9 user controls (Chart Control). And the the other tab pages contains single user control respectively. While rendering between the tab pages, the first tab page is taking remarkably more time than the others. Please can any body let me know,  is there any way to equalise the time of rendering between the pages by decresing the time taken by the first tab page?

Thanks and Regards.
