hyperthreaded?

[Matthew Dillon]

::The guy who gave me the box says he has another one like it, but one is 
::hyperthreaded and the other isn't. Here's the beginning of dmesg. Is it 
::hyperthreaded, and if so, should I compile a kernel to take advantage of it?
::
::CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2793.02-MHz 686-class CPU)
::  Logical CPUs per core: 2
:
:    Yes.  It has 2 real cpus and 2 hyper-threads per real cpu (4 total).
:
:    Definitely worth running a SMP kernel.  Even things like the atom
:    with one real cpu and 2 hyperthreads is worth running a SMP kernel
:    on.
:

    Oops, I've been corrected.  That baby has 1 core and 2 hyperthreads.

    In anycase, it is worth running a SMP kernel on it.
