Performance gains don't seem limited to just FF, so...
The only exceptional thing is that webpages require the use of some advanced rendering methods from cairo, which might in turn trigger driver bugs. (similar situation like with pulseaudio)
Do you have some options in xorg.conf maybe? I also use Arch Linux and after upgrade, Firefox became less responsive - it hangs sometimes for a second or so. I have this in xorg.conf:
Option "AccelMethod" "EXA"
Option "ColorTiling" "on"
and I have KMS disabled right now.
gears is HIGHLY cpu dependent, so if you upgraded your CPU that may explain the increase. Also if you upgraded mesa, there have been a lot of improvements over the past few months.
Again, it was a very sudden increase for me (and I think the OP too). I've been updating mesa and radeonhd pretty regularly, at least once every few days. We were just wondering what caused the gain. (I'm definitely not complaining.)Also if you upgraded mesa, there have been a lot of improvements over the past few months.
I just realized the OP was talking in FPS and gears shows frames in 5.0 seconds. So that gives me about 2000 fps with KMS. I checked without KMS and I get about 4000 fps in gears. This seems to make sense because Pentium D's are slow than most, if not all Opterons.
Regardless of this gears is not a benchmark stuff. When the graphics system is slow it makes it feel like the whole OS is slow. The recent updates in the last few months have made the desktop look and run so sexy smooth now.

But luckily they started rewriting interface - this work will give us the interface of Office2007 in just 3-5 Years
