I have some more observations:

1. I tried gnome-shell for a day, and at one point glxspheres was
suffering in performance, but not as badly as under compiz. The
animation was periodically freezing for a half second - it would then
report one (say) 40fps reading, and then immediately jump back to 59fps.
I didn't notice any slowdown in the UI, though.

2. Today in compiz I had the slow window dragging issue after a few
hours of use, ie when you drag a window it only moves the window
jerkily, and if you move the mouse too fast the window stops moving
altogether. However, and perhaps strangely, glxpheres reported a
consistent 59fps. Animations were slower than usual although the super-S
and super-W animations were still nice and fast.

The only odd thing that had happened in the session was that compiz had
earlier lost track of a window while I was dragging it when another
window was opened - I had to manually kill the process and restart it
because compiz couldn't re-display it.

I tried a ps auxw |grep compiz and it reported 721 MB VSZ and 71MB RSS,
whereas after startup it's more like 800MB and 120MB.

I'll try the PPA version to see if it helps.
