CPU utilization

All:
I have probably an old question that has been asked.. but
here goes anyway.
I have three machines.
1) stewart - running 7.0 (2.8gig p4 dual core)
2) bsd1 - running 7.0 (2.8gig Xeon Hyperthreaded)
3) bsd2 - running 6.2 (2.4gig Xeon Hyperthreaded)
Now if I run tests that max out cpu (at least I think
they do).. I see <1> or <2> drag down to 1% idle/ even
0 %idle.
However <3> never drops below 50% idle.. it preforms
a lot slower too.. which I expect since it is somewhat
of an older processor.. but in running say
top -S
I see CPU 1 always running the idle process...
Is this an accounting error that is being seen? aka top
does not know how to display things .. or is this a
scheduling error.. i.e.. move to 7.0 and life will
be better :-D
Thanks
R
