I just wondering if my system configuration is right optimized just for music production:

Ubuntustudio 64bit 11.10 on a macbook 4.1

My first doubt is about the number of processes that I see after system startup:

Code:

I know I'll never use the bluetooth service to do music, so I disabled it permanently and the daemon is no more in this list.
Would you suggest me other things to do?
