Upgraded to 11.10 and using unity now. Leave machine on overnight - in am, machine is beyond sluggish.
Reviewing
system monitor / processes reveals unity-panel-service using 5.2GiB and compiz using 83.7MiB (I kid you not)
reboot and after two hours of use, unity-panel-service is at 23.5MiB, compiz is at 66.7 MiB.
