The number I am looking at for a difference is the milliseconds number. I assume that I want that to be lower. I see two things. First, I see that we seem to generate more global events than FireFox 3. That is probably a good thing. Second, I see that on my Intel based laptop FireFox seems to be doing things at about 12ms and Chrome at about 8ms. I want us to be faster and if you are seeing us being slower I want to understand how to reproduce the results.
