wio above 20% - is that high?

Is the wio below considered too high? One of the folks
here thinks that as long as there are ample CPU %idle,
it's fine. I think that wio is fine if it remains in
the single digit or spikes occasionally but not
prolong over a long period of time which in my case -
over 20mins. Also, I think because of the
high wio, the %usr remains low. 

Any thoughts?

thanks.
