Trivial benchmarks, observed but not timed.  How long it takes a
browser window to come up, how smoothly scrolling through a browser list
updates, delay between clicking on a category and seeing the list of
methods, etc.  The qualitative difference is striking.  I will see if I
can come up with some numbers, although I don't have a good idea of how to
automate such tests.

This is on a 1.4Ghz Athlon, under linux.

My guess is it may have to do with event handling and not display -
a possible clue is that all of the versions that feel more responsive also
have a problem where almost every keystroke is doubled.
