Thanks Bryce for looking into that issue.
I never tried using fglrx with EXA. the commented part is just a left-over of the time when I was using the radeon driver.
Here is the log with EXA enabled. it seems that XAA is still used. Weird. The same performance issue happens.
I also think that software rendering is used. glxgears eats 80% of the CPU when running. If this is true, why does glxinfo report direct rendering as enabled?
Looking at bug 206337, and using vmstat, I do not experience the same symptoms.
