Great insight into how much work they put into optimizing the browsing experience. I don't think any other browser manufacturer builds as much smarts, at the network level, into their browser as these guys. The difference in performance between Safari and Chrome, for example, is night and day. Safari has smoother scrolling, but Chrome loads pages faster every time thanks to this work under the hood. I don't even want to speculate on IE - I doubt they do anything along these lines.
One thing thats particularly interesting is that these same optimizations are utilized on Android
and iOS - even though iOS Chrome has to use the system supplied webkit rendering engine and non JIT Javascript, it's clearly faster than Safari at the network side, and you can really notice the pre-fetch activity at work (try browsing to cn ... and then just stop for a second..and then finish cnn.com, and watch what happens - cnn.com will load almost instantaneously, because Chrome, even on iOS, guessed that's where you were going to go)
Neat stuff!
