I've read that a number of times now, but I have trouble matching it to my perceptions. Can you point to a specific website where you notice that slowness and then describe what action is slower? (Initial load, clicking stuff, scrolling, etc.)

Just as an example, loading jslinux.org for me in Firefox is about twice as fast than in Chrome. That might be a special case of course, because it is a very special type of workload that probably is not common on other websites. But I would love to see concrete examples of the opposite.
