I also run it with idprio 5 and no other processes are idprio-ed (what
a word). The main performance impact can be seen here when the
machine is a nfs server. When copying the same stuff (360 files, 7MB)
from this nfs server via nfs, it takes 39 seconds when rc5des is running
and only 7 seconds if not.
