(Perhaps I have higher resolution photos in my timeline.) > Btw, what tool are you using that tells you what item is being > repainted when the cpu is pegged? Mac OS X ships with a performance analysis tool called "Instruments". Documentation overview: https://developer.apple.com/library/wwdc/ios/#documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/Introduction/Introduction.html#//apple_ref/doc/uid/TP40004652 Recent WWDC presentation: https://developer.apple.com/wwdc/schedule/details.php?id=310 Instruments analysis doesn't work very well with the current shipping version of WebKit, but it works great with WebKit nightly builds (nightly.webkit.org).
