    Ok. I have something here that I find strange in transfering files. If I transfer files from one computer to another, windows machine to windows machine, or windows to Samba server my file transfer speeds are really slow. I referred to this on another thread blaming my router but I've come to the conclusion that it can't be my router.

    Here's why. If I ftp files I can get ~9000 kB/s going from a Windows machine to my ftp server using SecureFX as my ftp client. If I transfer a file from a Debian machine that doesn't run a gui to my ftp server I can get ~10000 kB/s. Now those are very good transfer speeds on a 100 mb/s lan. I can't complain about that at all. It's far better than I should expect to get.

    At first I thought my slow file transfer speeds using means other than ftp were due to the AV I had running on my Windows machines so I disabled the AV and then transferred files. It made no difference at all. File transfer speeds were still as slow as molasses. This happens with shares on Win2K Pro, Win2K Server, and Server 2003, and Samba. FWIW the Samba machine is very old and slow, but it is the one that I achieved ftp upload speeds of ~10000 kB/s.

    I'm wondering if this is related to some of the later service packs on Windows 2000 because I could copy a shared file a couple of years ago at speeds around 5000 kB/s, with the AV running.

    Has anyone else run into this? Does anyone know why the difference in speeds? It's not such a big deal, but it sure is strange.

    Not sure if this could be the cause but what about the Quality of Service bit in the NIC network properties ?


    could this cause it ?

    I don't use QoS on anything. It's disabled on all NIC's that have it as an option and disabled in the router configuration.

    Are the NICs set to 100/full or 'auto' ?

    I'm changing a lot of NICs at work from 'auto' to 100/full manual.

    If the nic's not duplexing were the problem all protocols would run at the same speed--slow. The way it is one protocol is much faster than another, 4x faster. I fail to see how that could possibly be related to a nic not duplexing in auto. But, I've been wrong before, so if you can show me how it's possible I'll explore it.

    Wow! Now that's what I call a find. That registry hack cut file transfer times using Explorer down to very comparable with the ftp file transfers times.

    Good research Pete. You da man!!! :respct
