hi there,
i'm trying to decipher the following top(1) output:

does this mean that
a) my system is 100% idle, since no processes except the idle process takes up
up CPU time or
b) that a or some processes take up 2% CPU time which aren't being shown or
c) that each of my cpu core is only 86.6/89.4% idle?
cheers.
