    Holger,

    you are absolutely right...

    I was looking at something else.

    Transmit Statistics: Receive Statistics:
    -------------------- -------------------
    Packets: 26077071 Packets: 34505652
    Bytes: 7521873507 Bytes: 2496050342
    Interrupts: 2 Interrupts: 31487067
    Transmit Errors: 1 Receive Errors: 0
    Packets Dropped: 1 Packets Dropped: 0
                                                  Bad Packets: 0

    I was looking at transmit statistics (on the other machine).

    Thank you for your help and for your explanation on the interrupts (it does
    make sense ).

    Peace.

    normally # of interrupts is a bit less than # of pakets (valid only for
    receive)

    how shell a card notify the os (its driver) that it received a paket? it
    can only by generating an interrupt

    its hard to believe for me that you have another card with no
    interrupts. can you post the complete output?

    Hi all,

    I have a network en0card that is having a high volume of :

    ransmit Statistics: Receive Statistics:
    -------------------- -------------------
    Packets: 20053539 Packets: 26199157
    Bytes: 1914061530 Bytes: 1865238706
    Interrupts: 9 Interrupts: 26027522
    Transmit Errors: 7 Receive Errors: 1
    Packets Dropped: 0 Packets Dropped: 0
                                                  Bad Packets: 1

    the card is set to Half duples.

    I do have another identical machine (lan settings the same, no the same)
    but no Interrupts. Could it be some problem with the lan card (hwe)
    itself ?

    thank you,
