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.
