I did not think so at first, but your problem is indeed memory 
consumption.  I am not, however, at all convinced that compiz has 
anything to do with that.

However, as shown here, your total memory commit is over 9 GB, (and your 
commit limit should be 5 GB, which means your in territory where the 
kernel will feel free to start OOM killing, which would explain your 
periods of 'freezing up' while memory is sorting itself out.)   This is 
really not normal.  *Something* has to be grabbing all that memory.

Maybe if you show us the output of a "ps -ely" someone will be able to 
spot one that's out of touch with reality.
