Hardware To Achieve Gigabit over PPPoE



  • Hi All,

    Our ISP has ran fibre to our location and requires us to authenticate via PPPoE to get online.

    Here's the proposed set-up:
    Fibre -> GBIC -> Switch (vlan 35 tagged) -> pfSense (currently a consumer grade router)

    My consumer router (ASUS RT-N66U) can get close, but it's bottlenecked by the CPU.
    Throughput during a speedtest:

    CPU consumption during a speedtest:

    The end goal would be to get rid of the consumer router and replace it with a pFsense server. I know that PPPoE on pfSense is single threaded which might pose an issue, which is why I created this thread.
    I would appreciate if some members of the community could share their pfSense hardware build to get as close as possible to gigabit speeds on their WAN link over PPPoE.

    Thanks,
    SqueezedJuice

    You will need some em Intel NICs and/or CPU that can do 1Gbps  on one core, some i3 should be good.



  • I was thinking only the igb driver is affected.

    em or ix should be fine, right?





  • I'm running:

    • PF 2.4.3-RELEASE-p1 (amd64)
    • CPU: Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (usually clocks itself down to 800mhz)
    • Intel® Ethernet Converged Network Adapter X550
    • 32GB RAM

    I run PPPoE w/ VLAN and I can speedtest to 950mbit/s. The CPU is 1-2%, RAM ~6% (running cache and ramdisk).

    I'm beginning to suspect I may have over spec'd the hardware.
