Just done a couple of tests and it seems to be a bit quicker but it's hard to say as I get a big variation depending on time of day and the weather.
The big difference I can see is in the speed that pages are rendering.
p.s. just tried a flash game that my wife says I waste too much time on and that's displaying noticeably quicker as well.
