The real answer is not too helpful Im afraid. You cant tell.
Basically treat the other CPU's as overspill so 4 * virtual
CPU's =~ 2.4 real CPU's at the very best. Neither Linux
or windows gives particularly accurate usage stats for
these CPU's. The more loaded however the closer it will
be to the real usage. So in your case 90% of the CPU in
top represents 90% of the virtual CPU.
Don't extrapolate directly from this that you can run 4*
said server on the machine though as you will find that
process may well be jumping between processors real
and virtual. Keep a close eye on the machine idle percentage
if it gets much below 20% the servers will start to exhibit
"lag".
Hope this helps.

I have a dual Xeon 2.8 setup and I have a few questions about the hyperthreading. With
it being listed as 4 cpus, HLDS will use
one of the four. Obvoiusly, two of these are not real, but HLDS uses the fake ones
anyways. My question is if the HLDS is on one
of the fake cpus and using 90% of it, is that using 90% of the whole cpu or just 90%
of the fake one?
What I am saying is if one of the fake cpus is full does that make the whole real one
of them full or does it split like 1400mhz
into the fake one?
