310MByte just for Compiz?.... Are you sure about this value? It seems quite high to me... Anyway, it is not necessary at all, I never use it and everything is snappy and fine :) You can un-install it by Synaptic manager, or you can just go to System -> Preferences -> Look & Feel --> Visual Effects and select "None".

It seems that he uses too much memory (310M) and CPU time. How can I disable it ?
