I just realized the cause of this slow-down is Unity (which is a plugin of compiz). If I disable the Unity plugin in CCSM, obviously the launcher and panel disappear, but instantly the frame rate of glxspheres64 and glxgears increases to the same as in Unity-2D or Gnome Shell.

ORIGINAL DESCRIPTION: A recent update to compiz in oneiric has had a big impact on 3d performance. The desktop feels more sluggish, and the glxspheres benchmark indicates about half the performance compared to metacity and mutter (on my Sandy Bridge GPU I get 30-32 fps in unity/compiz vs 59-60 fps in both unity-2d/metacity and gnome-shell/mutter). Previously compiz matched the performance of metacity and mutter. I also tested the oneiric beta2 live CD (amd64) and performance was similar (ie regressed compared to beta1).
