The standard tool for benchmarking 2D X stuff is x11perf. It tests lots
of core protocol stuff, i.e. not the stuff that's really important in
terms of performance these days. These days the X Server is spending a
lot more time grubbing around in framebuffer memory (really, really
slow) due to the lack of Render acceleration.
3D probably isn't important to test, as it's all done client-side
(almost no IPC) if you've got acceleration. And never use glxgears for
benchmarking the 3d drivers or I will have to beat you senseless.
