sg-3100 500mb limit iperf test



  • Hello

    I have a sg-3100, and noticed that during the IPERF test, I can only reach 500mb as per image below.

    It seems that the bottleneck is the CPU

    Is this normal for the sg-3100, or there is something wrong?

    We need some more details on what is going on.

    Looking at the screenshots, your iperf server is on pfSense, you don't want that. You need to run the server on another device.

    Don't run iperf on pfSense, this isn't going to test routing throughput. Run iperf on devices connected to WAN and LAN.



  • ow, used sg-3100 as client of the iperf
    and the history is different now:


    Client connecting to 192.168.255.250, TCP port 5001
    TCP window size: 64.2 KByte (default)

    [ 3] local 192.168.255.249 port 48963 connected with 192.168.255.250 port 5001

    Thanks very much guys
