Slow throughput on new install.



  • Hey all,
    I just finished setting up my pfsense 2.2.6 virtual install on a esxi box.  I am getting:

    Comcast Router in bridge mode direct to PC: 178.04 mbps down / 12.10 mbps up
    Comcast Router in bridge mode to esxi box to PC (no switch): 58.86 mbps down / 12.17 mbps up

    Does anyone have any ideas why I am losing so much bandwidth?  I tried all of the troubleshooting in the docs (disabling the hardware checksum offload, etc) and all to no avail.
    Thanks,
    JP

    What is the ESXi box? Is it a HP server? Perhaps a proliant Gen.x server from HP?
    I ask for it because HP has its own ESXi image that is working fine together with the
    HP Proliant Microserver Gen.x and you should go with it if it is in this "game".

    This means that the comcast router is acting as a pure modem!!!! And there fore there will be no
    SPI & NAT at all, please don´t forget this! And if pfSense is in the game then on top you must count
    the firewall rules that need also their time.

    Is there perhaps any auto negotiation miss match that is dropping down your throughput likes a 100 MBit/s port.

    What you are all running in this pfSense firewall? And how strong it is equipped
    from the hardware tech specs. I mean?

    I would try out at first to set up a small 5 Port or 8 Port GB LAN switch between the router in modem mode
    (bridged mode) and the WAN port of the pfSense to be sure that all is negotiating up with 1 GBit/s continuously.



  • I feel like an idiot…The problem was the cable.  It was a cat6 cable that had been in use for a while.  I swapped out the cables and now I am running like 120 down and 12 up.  Still not perfect, but much better.  Sorry for the oversight.

    Ok pending on the numbers of 120 down and 12 up it would be more owed to some other things
    inside of pfSense or perhaps the point of running in a VM. You could try out the following;

    • high up the mbuf size
    • enabling PowerD (hi adaptive)

    On top of the 120 down you must count the TCP/IP overheat and the passing through of NAT and firewall rules
    what can narrow down the entire throughput also really hard, oending on the system tech. specs. likes CPU
    horse power and amount and speed of the RAM.
