The mysterious case of the 82Mbps PPPoE upload

MatthewHaigh

Hello there,

I have just migrated over from UTM and would love some help with a curious case of why my PPPoE connection refuses to upload faster than 82Mbps.

I have a 200mbps down and 200mbps up fibre optic connection.

The PPPoE interface and LAN interfaces have gigabit negotiated. QoS is ok. Download speeds exceed 200Mbps - but I cannot replicate on the upload.

The 82Mbps sounds very much like the expected rate if the cable was 100mbps - but no, the system confirms gigabit negotiated.

I have checked all the cables with a cable tester - all ok.

I plugged in my old mikrotik router, and it managed to get 180Mbps in both directions before topping out of CPU - so it is not my fibre connection.

Using dedicated quad core pentium 2.6Ghz with 8 GB of RAM - system is idling under load.

Can you help - is there something odd going on here?

Any tips on how I could test the upload speed and / or correct?

Thank you kindly.

    I see you never got any help on this... maybe I will, who knows.  :)

    I'm using the software (Hyper-V) XG firewall and provisioned it with 4GB RAM, 2 CPUs and it's the only VM running on a Precision 3500 with Xeon E5506.  Recently upgraded to a 150/150 fibre connection and although I can get about 160Mbit download I can't get over 30Mbit upload.  When installed, connecting before the firewall would test about 162Mbit down and 150Mbit up.

    A separate firewall on the network, a Cisco RV220W is limited as well, but at about 85Mbit down and 85Mbit up.

    Any ideas as to why the software firewall has trouble with upload speed, no problem with download?  Using the latest firmware (SFOS 15.01.0 MR-3 448).

    Guess I should post this as a new thread (will do).

    Changed hardware, may have been PCI add-in gigabit card causing problems - moved from Realtek to Intel. Moved to pfSense and works fine. Likely to be a driver/linux issue.
