I feel this is affecting me as well, but I think it did not earlier,
just a week or two ago in lucid. I wonder if some of the kernel intel
changes have caused this major performance regression or what. Too bad
the older kernels are not available anymore!

Is your lucid a very new installation or have you been using lucid for
some time already? I wonder if eg. http://kernel.ubuntu.com/~kernel-
ppa/mainline/v2.6.34-rc3-lucid/ should be tested.

For the record, I have GM965 ie. GMA X3100.

+ I think this would be a kernel regression with intel performance. Even

+ X.org driver and 2.11 from xorg-edgers.

  Binary package hint: compiz
  
  Desktop effects are noticeably slower while Firefox is open. My display
  adapter is an integrated Intel® Graphics Media Accelerator 4500M. I
  tested this using the built in Benchmark plug-in.
  
  When Firefox is not running I get a solid 60fps (vsync is enable I
  believe). Having a few GTK+ applications (such as nautilus, gedit.. etc)
  open does not slow the frame rate even when running the expo plug-in.
  Running Firefox causes a noticeable slowdown in the expo plug-in and
  desktop switching. The frame rate drops to 30fps and below and feels
  choppy.
  
  I have not modified the configuration of either compiz or my intel
  driver. I am running Lucid on AMD64. This occurs on both the Generic and
  the Preempt kernels.
