1gbp networking LAGG speed problem



  • Hi,

    Ive bought a new firewall from pondesk here in the UK its the MNHO-048 model. Intel ATOM E3845. Ive created a LAGG and bonded all ports together but the issue is speeds. running iperf from the Firewall to a Workstation or Servers im getting full gigabit speed but running from a workstation or Server to the Firewall im not even hitting anymore than 500mbps even the CPU is not pegged out, It has 4 I211-AT which are Gigabit.

    Any ideas?

    Thanks.



  • Ive done some tweaks. it was working but then the speed has just dropped again.

    Tweaks ive done.

    Disable hardware checksum offload

    Disable hardware TCP segmentation offload

    Disable hardware large receive offload

    add the following to system turntables

    kern.ipc.nmbclusters="1000000"
    hw.igb.rxd="4096"
    hw.igb.txd="4096"
    net.inet.tcp.syncache.hashsize=1024
    net.inet.tcp.syncache.bucketlimit=100
    net.isr.defaultqlimit=4096
    net.link.ifqmaxlen=10240
    hw.igb.rx_process_limit="-1"
    hw.igb.num_queues=2
    dev.igb.0.fc=0
    dev.igb.1.fc=0

    but performance is still horrible and im only getting 20mb/s over VLANs yet on old firewall i got 70mb/s any ideas??



  • Anyone? Ive tried other tweaks but no go. Routing and VLANs are not wroking correctly nether is LAG.



  • After many tweaking and trying different things. I knew this wasnt a Network problem this a problem caused by the CPU in Low Power Mode i.e CPU stuck in one Power State, Enabling PowerD fixes this set to Hiadaptive and reboot with the following Network Tuning and watch the Performance go up.

    Disable hardware checksum offload

    Disable hardware TCP segmentation offload

    Disable hardware large receive offload

    add the following to system turntables

    kern.ipc.nmbclusters="1000000"
    hw.igb.rxd="4096"
    hw.igb.txd="4096"
    net.inet.tcp.syncache.hashsize=1024
    net.inet.tcp.syncache.bucketlimit=100
    net.isr.defaultqlimit=4096
    net.link.ifqmaxlen=10240
    hw.igb.rx_process_limit="-1"
    hw.igb.num_queues=2
    dev.igb.0.fc=0
    dev.igb.1.fc=0

    Thanks for the updates.. Never heard of these guys before. But interesting platform.
