Gecko runs slower, less capable, and doesn't adhere to the standards as strictly last I checked. So they aren't "exactly" the same.

Gecko is also very very wide spread in other non-browser applications AFAIK.

I was under the impression that Gecko was sometimes slower because it implements standards better than Webkit.

"This is not exactly an isolated incident; a number of the performance issues I've run into recently in Gecko have had to do with correctly handling edge cases that this particular open-source engine happens to just not handle. I guess it's easier to do well on tests if you cheat.

More interestingly, Opera's performance on this sort of thing is still quite good, and I have yet to discover them cheating..."

The comments are good too, and include input from Dave Hyatt, but you have to skip over the "contributions" of some aggressive webkit fanboys.
