It's decent, but Firefox seems a lot faster. Completely anecdotal of course.

edit: not sure why I'm being downvoted

There was an article only the other day about how firefox is faster, on the front page. I've even switched to it (for a few days, to see) myself!

Same here.

In particular, page rendering and repaints appear noticeably faster in Chrome than in Firefox of Opera. However, I notice the difference more on Linux than I do on my Windows machine.
