I have an Intel Xeon 3 gig CPU and have hyperthreading turned on in the
BIOS. I've been trying to work out what the advantages and
disadvantages of this are.
The CPU appears as two CPUs to the machine, which means that
non-threaded apps don't appear to use the whole CPU. Is this a correct

My understanding (from uni cpu architecture) is that Hyperthreading
(descended from supathreading) essentially straps a second control unit
to the instruction portions within the cpu and then links it to the
other control unit.
It can therefore pretend to be a second cpu by utilizing the

Thanks for all the informative responses. So it seems there's only a
minor performance decrease from having hyperthreading enabled if load is
a single thread. i.e., my reading of top wasn't right.
Thanks again.
