slightly OT - X performance benchmark

[David L <idht4n gmail com>]

My f11 system seems extremely slow when running
some 2D gtk/cairo apps.  Is there a benchmark
suite that is yum installable for testing X performance?
If there is such a suite, it there a way to compare my
results with typical results for similar graphics cards
(maybe something like smolt but with benchmark
results)?

I'm mostly interested in 2D performance.

Thanks,

            David
