    Go download it and try it, then come back with that smirk wiped off your face.
    I'll enjoy it.....

    And as I told, you, your code has nothing to do with it, it's the fact it
    goes on at all. Ingo, go get a copy of NetWare 3.12 (I'll even send you
    one -- I've got extra licensed copies), install it, put a load of 5000
    connections on it, with 4 adapters. Dual boot Linux on it, and attempt
    the same with SAMBA or MARS-NWE, and watch it oink.

    Go do it. What's your address to I can ship you the CD's for 3.12. Then come
    back and tell me how TUX is going to solve the File and Print performance
    issues in Linux.
