I only have to say "Sorry, I don't know" for this question. :-)

I hope other more experienced folks in this list will help you. 

I can give you just a thought however. If you have such massive requirements if 
I were you I would do the socket handling inside the kernel itself.

That way you avoid the very expensive user space/kernel space context switch 
and also go in for some embedded system suited for this sort of thing.

Perhaps I am talking rubbish. If so please pardon me. :-)

Best of luck!
