I'm I the only person on the planet using ubuntu that experiences
changing of performance? After using the pc for anytime from 1 hours to
6 hours, when performance is generally sluggish on flash video and
firefox scrolling, out of nowhere performance just explodes and
everything starts working great. I tried to have a look at various logs
but nothing really stands out as to reveal what happens.

I tried the recommended xorg.conf configuration on an ATI Mobility
Radoen 9700 running radeon driver, lspci describes as:

01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility
Radeon 9600 M10]

And saw no visible increase in performance. Xorg.0.log reveals this
weird sequence though:

(**) RADEON(0): Option "AccelMethod" "XAA"
(**) RADEON(0): Using XAA acceleration architecture
(II) RADEON(0): XAA Render acceleration unsupported on Radeon 9500/9700 and newer. Please use EXA instead.
(II) RADEON(0): Using XFree86 Acceleration Architecture (XAA)

I guess the XAA parameter passes, it's in use, but... maybe it's not?

No one with the same graphics card/chipset (300s series) sees this on
the log?
