Core(TM)2 Quad and TOP output

Can you provide some more detail here? How is it slower? Serving less
clients? The load (from your top snapshot) is nearly 0 and there isn't
much of a memory load on the box either.

Run top with the -S option, and you will see the "idle" process for
each core/CPU. The CPU: line there is an aggregate of all processors
in the system.

If you're in doubt:

sysctl hw.ncpu

Or run:

mptable

Yes, 7.0 includes SMP by default in GENERIC.

There you go, it's seeing all 4 cores.

The system is seeing all of them, so your real question is likely -
why is this not performing as well as my old box? We need more details
to answer that.
