I found this via search for "firefox css performance"

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/223238

It sounds like FF is doing something with X, that the Nvidia drivers
don't do well.  That's the only combination that seems to be consistent.
That's the proprietary Nvidia drivers, not the opensource ones.

I don't have Opera installed, but it sound like Opera doesn't have the
same problem.

The hardware matches my setup, Dell Precision T7400 Dual Quad Xeon @
2.00 GHz/ 16 GB/ NVidia Quadro FX 1700 running RedHat 5.2 Desktop and
the proprietary NVidia drivers, and scrolling of a long RT Ticket really
hammers the machine.

Another result from "Firefox Nvidia scrolling'

Example page scrolls incredibly slow ( I have no idea what it says,
sorry if it's offensive): http://www.tempus-vivit.net/taverne/thema/935

I couldn't find anything specific to moz-border-radius, but now that
I've seeing so many example website perform so poorly under FF3, I think
I'll be installing Opera.
