Hello,
What exactly do you want to show/tell us with this? Yes the idle times
are unbalanced, some CPU's can be more busy then others, and thus have
less IDLE time recorded and less CPU spending on being idle (sounds
contradictive :-)), but I do not see that as a problem, remember that
there are unthreaded applications that just work on a single CPU , which
might have been CPU3....
Thanks,
remko
