Great, done that.
Saw already that the igb-options.conf fix is already in the latest rolling version!
So pleased I can squeeze 1gb/s from the APU2, meaning I don’t have to reinstate my Edgerouter…
Thanks for the awesome support.
Just applied a new rolling release. Back down to 550-600 mb/s.
Seems similar to my original setup even though all changes are in place on my router. Sadly I deleted the previous image already so cannot roll back…

Hello @phillipmcmahon,
Show me please an output cat /proc/cmdline and screenshot cat /proc/interrupts
Just performed another set of speed tests and the results are very inconsistent. Occasionally getting up to 900mb/s.
Output attached.

I don’t see disabled mitigation on your booted cmdline
Try to update initramfs
sudo /usr/sbin/update-initramfs -u
And check after reboot /proc/cmdline again
yep, had done that a few times.
just did one more time, rebooted.
output of /proc/cmdline is still missing the entry
cat /proc/cmdline
BOOT_IMAGE=/boot/1.3-rolling-202010200146/vmlinuz boot=live quiet rootdelay=5 noautologin net.ifnames=0 biosdevname=0 vyos-union=/boot/1.3-rolling-202010200146 console=tty0 console=ttyS0,115200
Try to put this like an example, after boot=live:
menuentry "VyOS 1.3-rolling-202010200146 (KVM console)" {
linux /boot/1.3-rolling-202010200146/vmlinuz boot=live mitigations=off quiet rootdelay=5 noautologin net.ifnames=0 biosdevname=0 vyos-union=/boot/1.3-rolling-202010200146 console=ttyS0,115200 console=tty0
initrd /boot/1.3-rolling-202010200146/initrd.img

yep, just did it like that and this time it is being picked up.
back in business! thanks a lot.
p.s. why previously did that work and now not?
I don’t have an answer, maybe something was different. I prefer always recheck cmdline after reboot or update.
thanks! appreciate the help. I should know what to look for in future.
@Dmitry There’s so much great info in this thread - hopefully it can be added to the Vyos wiki so that future users don’t have to search the forum to find it?
I certainly learnt a bit, I wasn’t aware about the ntuple feature.
Humm. It’s weird that you have to do all these configuration to get the 1gb full speed.
I use a lot of Mini PC Quad Core J1900 2GB RAM with 4 LAN Ports and I have no problem to get full gigabit speed with PPPoE.
Be sure that your LAN ports are Intel ones. With Realtek NIC I got problems and I was not able to get full gigabit speed with it.
The PC Engine APU2 is an SBC with an AMD SoC running at a max of 1 Ghz - 12 watts. They run Intel NICs but it wasn’t a great surprise the thing needed some tuning to get full 1gb/s speed out of it.

Super nice boards;
Oh Ok that’s why! 
I don’t know how much is an APU2 but a Mini PC is about 200 USD
It’s about the same 
I am looking at getting a Protectli box, but believe this is “just” a rebadged qotom machine.
Feel free to ping me if you have any recommendations for a good low power, silent box. Ideally I would want something that can take a 10gb/s sfp module as that is what comes into my apartment…
I also got an APU2 board, not sure if you got following settings allready (do this for all NICs) and reach somewhere around 920Mb/s.
ethtool -G ethX tx 4096 rx 4096
ethtool -K ethX tx on sg on tso on gso on gro on lro off
- line set ringbufers to max.
- line turn on offloading
I put the commands in /config/scripts/vyos-postconfig-bootup.script which is run at boot.
And don’t have mitigation=off set.
