PPPoE WAN

I was testing other VMs:
- Debian to Debian on same network reaches 20Gbps
- vanilla pfSense 2.8.1 to Debian 4.46 Gbits/sec
- also vanilla FreeBSD 16.0 (Current) to Debian - and that's what worries me, because I get 17Gbps one way, and 5Gbps other way.

Does it mean that even in near future I won't achieve over >15 Gbps speed on OPNsense/FreeBSD?
Or haven't setup up sth obvious?

Are these all PPPoE speeds ?

If so, I think there is not much you can do about it : Anything Linux based will perform simply better when using PPPoE on your WAN :)
