Well I just tried glxgears here on my Intel 2.4G P4 with nvidia NV44A 
(Geforce 6200) and got a whacking great 15FPS if I hid the gear window 
behind the console window and about 8 FPS in the open.

So 'glxgears is not a benchmark' is quite true. This system plays an HD 
test clip of tennis in xine using about 50% CPU total: about 40% xine 
and 10% X...

But here is your real problem and a REAL speed up for you.
Run glxgears and note your FPS.
Run ps-ae and note if you have any acroread processes running.
Run killall acroread.

Now re-run glxgears..... Mine jumped to 1275!!!!!  My Via SP13000 board 
at home has topped out at 796 FPS so 1279 fps  is just right.

If you have suffered from slow screen reactions while in Firefox it may 
be because the acroread plugin is a cycle stealing piece of crap.

Do 'cd /usr/lib/mozilla/plugins'
Then 'mv nppdf.so nppdf.so.old'
Then open an instance of firefox, open any page you like, pull up a 
console over that, try glxgears and get 1280 fps!

That fixes the problkem at the expense of not being able to open pdf 
files natively in a browser window. You will have to select to download 
the file, and save it or open if with xpdf or gsview etc.

Cost in mouse clicks to do this: 2
Extra time to do this: 2 seconds
Effect on computer speed: priceless.
