> I already did: socketcall Got anything that applies to modern platforms or recent kernel versions? Also, does socketcall actually have higher overhead than doing a similar dispatch in userspace, or does it just mean you get a cache miss slightly later in the process? (You could try elucidating an actual argument rather than just naming a syscall and assuming that the rest of your argument is obvious.) > And NT does all 32-bit compatibility in userspace. So? Is it faster to do that in userspace than in the kernel?
