Hello all,
        
        I have a 100 Mb network and I have detected too many collisions when
accessing from NT to my linux machine. When I transfer files between NT
machines, performance is quite good. When I make a ftp connection from
NT to linux and get files, transfer is good, but when I put files,
transfer goes down and too many collisions occur.

        I have made some tests with ftp program from a NT machine.


        NT      -->     Linux           (ftp PUT)
        
        (*)   10 Mb     425 MB/s

        (**) 100 Mb     180 MB/s


        Linux   -->     NT              (ftp GET)

        (*)   10 Mb     1025 MB/s

        (**) 100 Mb     3300 - 4700 MB/s


        (*) I have a SMC 10/100 Switch and a 3COM 10 Hub connected to it. My NT
ethernet card is configured in AUTO mode, so I can connect this machine
to the hub or the switch.

        (**)    NT ethernet card is a LongShine 10/100
                Linux ethernet card is a D-Link DFE 530 TX


        I have also tested NT to NT transfers. They are quite good, but I can't
measure them. I suppose near 4000 KB/s


        I appreciate any help from you.

        Thanks,

                Cristobal Bonillo
