This issue, I believe, is well known:
http://www.phoronix.com/scan.php?page=articleitem=ati_ubuntu_kmsumsnum=1
In my opinion this bug should be renamed to something like: degraded
performance of KMS vs UMS
And perhaps it should be put in wishlist and sent upstream.

This issue happens to me, too. It is most definitely not solved.
There is nothing to solve in this report, glxgears is not a benchmark,
so having a slow glxgears means nothing. Moreover, you're not even
using

Please reread my message. I am experiencing poor performance in
AisleRiot and ZSNES as well.
This bug report was about glxgears, not about these.
This is when KMS is *on*; I experience no
such performance issue when KMS is off.
Why did you send the log with KMS off

Package: xserver-xorg-video-radeon
Version: 1:6.12.191-1
Severity: normal
With KMS and DRI2, glxgears is dramatically slower (about 140 fps)
than without KMS and DRI2 and with only DRI (about 300 fps). Also, the
motion is not uniformly smooth and seems to depend a lot on the
background system

Alright, I admit this bug is invalid. I've
