My first implementation used existing kernel code and showed small
performance win - there was binding of the socket to netchannel and all
protocol processing was moved into process context. It actually is the
same what IBM folks do, but my investigation showed that linux sending
side has some issues which would not allow to grow speed very noticebly
(after creating yet another congestion control algo I now think that the
problem is there, but I'm not 100% sure).
And after looking into Van's presentation (and his words about
_userspace_ protocol processing) I think they used own stack too.
So I reinvented the wheel and created my own too.
