    Thanks!

    Yes.

    It's not so important.

    davem> Personally, it seems rather essential for scalability on SMP.

    Yes.
    It will be effective on large scale SMP machines as all kNFSd shares
    one NFS port. A udp socket can't send data on each CPU at the same
    time while MSG_MORE/UDP_CORK options are set.
    The UDP socket have to block any other requests during making a UDP frame.


    Thank you,
