Actually the results using dri is worse than the results without dri in terms 
of frame rates. Without dri I get something like 250 FPS. With dri I get 
something like 228 FPS. The great difference though is when looking at the X 
cpu usage. glxgears uses around 0.5 % with or without dri. But without dri X 
uses 92% of the cpu resources. With dri X uses between 0.5 and 1% cpu. So 
obviously dri is preferable... ;)

Listed the output below if anyone is interested.

~$ glxinfo | grep dir
