Traffic is very slow between LAN interface and dedicated bridge card

  • Hi everyone,

    I'm newbie to PFS and the whole networking thing but I managed to setup and run PFS. Here is the specs of the hardware:

    • Asus Z97-K mobo
    • i5-4440 CPU
    • 8GB memory
    • 1 dlink card (1 gigabyte) card assigned as WAN interface
    • Mobo interface is assigned as LAN interface
    • 1 TPlink card (1 gigabyte) card assigned as bridge and dedicated for my unraid limetech server

    The issue: when I move a file from my pc to the server, maximum speed I'm getting for transfer is 11MB (very slow) but when I connect the server to the LAN, the speed about 110MB (normal/fast).

    I couldn't figure out the issue.

    Your contribution is appreciated.

    Thanks in advance,


  • You shouldn't use bridged interfaces as a replacement for a switch. It cannot work as good as dedicated hardware.
    I don't know the TP-Link cards and their chipset. Chances are, they are based on cheap Realtek chipsets. They are known to not work great.

    Just buy a cheap Gbit switch.
