SMB kernel is just fine for these. The hyper-threading chip is the
intermediate step between single core and true dual core. When the chip
is a dual core, there will be loads of marketing glitz advertising that
fact. For many server uses, the HT chips were more of a problem as the
L2 was thrashing. Thus the dual-core was born.
