I believe different things combined add to it happening. Such as on the
chubbs1111 link, the lag is being caused by two media plugins loading at once
on top of background fixed image and foreground images galore. Especially
notable on slower connections where the content is still loading while you're
trying to scroll. Doing some testing I managed to speed things up some by
removing simbl and safarisource plugin. guess rendering source coloring in a
hidden window helped to contribute some but it's still pretty bad. I tried with
smooth scrolling on and off it didn't seem to make much difference. Although
for some strange reason when smooth scrolling was off the quicktime media on
that profile caused a crash. 

Thread 13 Crashed:

But I don't think that's a webkit problem, looks like a definite quicktime one.

Like i said i think you just need to spend a good while browsing myspace for a
while. Maybe checkout a decent mac group there with over 10,000 members, see if
they can provide any insights.
