Hi, I am running Slackware64 14.1 with 3.13.6 kernel, radeon 6670, latest mesa 64 bits (forgot the number, I am not on my system now) and alien's bob mesa compat32 version. I decided to run the Phoronix benchmark tool and I tried the OpenGL test and I was getting 3 fps on it! Is is normal? I mean, for the free radeon driver? I wonder if I ddi something wrong while compiling mesa.
Not necessarily. The app could be 32-bits, your drivers could be just fine, but the benchmark might simply want functionality that isn't present in the free radeon driver.
If you've not got any games installed and want to put OpenGL through it's paces then you could give the screensaver hacks shipped with xscreensaver a go.

I am running mesa stock version now, will give it a try then upgrade to latest mesa and see if there is any difference.
EDIT: Oh, nvm, thought it was a more intensive task. Getting 30FPS and 72000 polys on it. Is that any good?
EDIT2: Slightly better perfomance with latest mesa, a solid 30FPS while the stock version was between 25 and 30. Not much but it is better than nothing.

If you want to see the true speed you'll need to deactivate SYNC to VBlank. Otherwise you'll get a multiple of 30fps.
__GL_SYNC_TO_VBLANK=0 /usr/libexec/xscreensaver/glschool -fps -delay 1 -nfish 250
That gives me 75fps with the nvidia blob, but that's probably limited by the fact that the glschool process is pegging a CPU at 100%. If I start a second instance, they both run at that speed so I suspect the graphics processor still has some headroom and my dual core cpu is the bottleneck.
It's not really intended as a benchmark, just thought it'd give you something to compare.

What video card you have? Because 30 vs 75 is a huge difference

checked this with perf
it is very cpu intensive (it calls pow() a lot)
i usually test with xonotic (tool comes with it)
but even that is more towards cpu bottleneck
