We need some talos help to get this as a reliable metric, but we should be able to get this soonish.  dtrace stats on chrome/chromeless would be awesome.

deltas on 1.9 branch as of 3/3/2008:

Vista: ~7-10% (numbers very noisy)
XP: 14-15% (much less noisy)
Linux: 3-5% (noisy)
Mac: 15-19% (not so noisy)

Not sure why Linux numbers are so much closer than Windows and Mac...
What were they in firefox 2?  How close are we to this?
As of today, Mac is down to ~8-12% delta, but I don't know about FF2.
Stuart: we don't have reliable numbers (or, more accurately, any numbers) for Fx2.  Pretty sure vlad was having problems with that even from the beginning (something like identical numbers with/without, which seems very odd, since we know there's _some_ cost to be had).
not going to block on this at this stage of the game, will try to take this the rest of the way during the next release.

Not sure what the right resolution for tracking bugs that aren't quite relevant anymore... -> INCOMPLETE

(We moved the needle, but we never reliable numbers on what we moved the needle _from_, so it's rather moot.  Work continues.)
