    Test network speed with iperf


    You can test your network speed with the program iperf. It runs under all most used operating systems. The windows binary file can be found here:
    https://nocweboldcst.ucf.edu/files/iperf.exe
    or
    https://nocweboldcst.ucf.edu/files/iperf.exe

    The file iperf.exe is used as client AND server.
    The basic idea is that the client UPLOADES an amount of data to the server.
    The speed of the transfer is then calculated.

    For a deeper introduction watch this Flash guide.

    An example:
    Server: iperf.exe -s
    Client: iperf.exe -c <server-ip>
    (Speed is now uploaded to the server)

    Use: iperf.exe –help to see options

    Test up and then down:

    C:\>iperf.exe -c 192.168.0.199 -r
