It does sounds like compiz' high CPU usage is probably why unity feels
slow. Could you please try gathering some compiz profile information
by...
1. INSTALLATION
sudo apt-get install linux-tools-common
Then you also need the package specific for your kernel. You can find out what
it is called by running "perf". That will tell you what you need.
2. RECORD PERFORMANCE
Start this and let it run for a while:
perf record -p `pidof compiz`
Then stop it with Ctrl+C.
3. CREATE A REPORT
In the same directory (where perf record created file 'perf.data'), run:
perf report > compizperf.txt
And attach the file compizperf.txt to this bug.
