Paging between UITableViewControllers is jerky

[ddmmcjmm]

I implemented the ViewPagerController, and each page is a UITableViewController that contains only about 30-50 UILabels. However, when I scroll between the pages, the scroll is not smooth and is quite jerky. I have made the contents array to hold more view controllers. But the problem persists. I suspect that it is not just enough for me to preload the surrounding controllers; perhaps I should also preload the views inside those surrounding controllers. Do you guys have any idea how I should approach the problem?
