(Get the code!)
I also see exactly the same behavior with Oneiric's Compiz and Radeon HD 3200 (AMD 780G chipset's integrated graphics). Compiz is a lot slower/laggier than it was in 11.04.
Testing with glxgears (leaving the glxgears window in its default size) on latest Ubuntu 11.10:
Compiz is at around 33-42 FPS
Mutter is at a stable 59.xxx FPS
Ubuntu's 11.04 Compiz was also at 59.xxx FPS (the screen's refresh is at 60 fps).
There is a chance that the fix in:

solves it, but i don't have a way to test it until a PPA of the fix for Oneiric is build.
I think that this is a very important regression because for the systems that it affects, Compiz/Unity becomes unbearably stuttery/slow.
