You may want to consider a related problem with the combination Compiz and Clamav. I did an upgrade last week from 10.04 to 12.04. After doing this, I noticed a significant slowdown in the performance, basically it became unusable for work.

Looking at system monitoring, Compiz was somewhere in the range of using 50% of one processor, but more significant Clamav (installed from the repositories in 10.04) was using close to or over 100% of one processor. I could fry an egg on the laptop. I killed ClamAv and then removed it using package manager. This improved things instantly, though I must say I still perceive it to be slower than 10.04.

Since it does not get hot anymore, but overall it is not great.

Hardware: HP Compaq 6720S, HDD320GB, 1 GB ram.
