Does anybody have insights into general performance implications of using UIWebViews vs Mobile Safari?

There are several, but in particular, JavaScript seems to run 2X slower in UIWebViews vs Safari. on iOS 4.3

From what I've been able to find, UIWebViews run as they traditionally have on 4.2, the JS just runs 2x faster exclusively in Mobile Safari, so no performance hit, just no gain either.
