    Hi Folks,

    I own a Via Epia Board with 500MHz CPU and have installed Linux from
    Scratch with vsftp.

    I started some benchmark with a 100MB file.

    connection from local machine with ncftp (three times average):
     get -> 6MB/s
     send -> 4MB/s

    I wonder why send is slower...in both cases the file is read and write
    from/to harddisk, but this is not the main problem.

    I also test ftp from a WinXP client (wsftp, 100Mbit LAN) :
     get -> 6MB/s
     send -> 200kB/s

    After analysis I found out that there are many dropped packages in RX
    from eth0. To solve this issue I set the window size from default to
    1024. If I set this higher than I get dropped ones.
    But this helps me to archive a send from 2MB/s.

    This is less than I expect.
    The VIA system is more or less idle when receiving the 100MB file. So
    the CPU speed is not the brake here....

    Does anybody know if the Onboard LAN of VIA Epia is that worse ?

    Best Regards
    ka-long
