"Netbooks" based on Intel's "Atom" microprocessor are turning into big hits this Christmas season. The Atom, a super-low-power x86 processor, is an "in-order" machine, which means that except for a few special cases it can spend a lot of time waiting for data to arrive when it encounters a cache miss. So, hyperthreading may make sense on this kind of processor as compared to one with out-of-order execution.

Which raises a question: What's the status of FreeBSD's support for hyperthreading?
for FreeBSD it's just like 2 processors.
