  The network-manager, cron, and other
 things we have heard about, when you get periodic xruns no matter which
 latency you use. Can we make all of those problems go away by changing
 rtprio for devices? 
No! There are services that we shouldn't run on an audio production
machine.
It's hard to say what should be disabled and what doesn't matter.
For example, I don't think this counts on my machine regarding to
performance
$ grep noatime /etc/fstab
/dev/sda11                                /mnt/music      ext3    noatime,defaults    0
2
/dev/sdb12                                /home/music     ext4    noatime,defaults    0
2
but on another machine noatime might have impact to the performance.
