Implementing CATiledLayer in a UIWebView for Fast Scrolling

I have a large webview in my iPad app, and scroll performance seems like a big problem, especially the first time you view a webview. On mobile Safari, scrolling is extremely smooth, and the page just looks like a transparent checkerboard pattern and loads when it appears in sight. From what I read, the way to handle this is to use CATiledLayer, but I have no idea how to implement this. Can someone point me in the right direction? Thank!

UIWebView should already be doing its own tiling behind the scenes. It is not possible to manually return a UIWebView with the CATiledLayer that I know of, due to its complex rendering architecture.

If you are creating a UIWebView that is only the size of the display, the only reason I could think of a slower scrolling than Mobile Safari is because there are other overlays that need to be arranged in the web view when scrolling.
