Yes, but who'll need them? You say that "engaging me" is useless, yet you dont make a point that has anything to do with what i said. My question is, Is it worth it to tear apart the FreeBSD internals and to significantly adulterate the kernel proper with SMP-specifics to sqeeze some extra performance in the wake of the forthcoming performance boosts seems counterproductive. We dont program in assembler (much), because the extra performance isnt worth the effort. Im not saying that SMP should not be supported, only that making the OS and drivers more cumbersome for a small performance boost may be counterproductive in the long run.
