Hi, thanks a lot for claryfing this, I'll keep it disabled.
BTW, I tried all the reccomendations I found in this page:
https://docs.netgate.com/pfsense/en/latest/hardware/tuning-and-troubleshooting-network-cards.html
but still cannot get more than ~5.5 Gb/s from my Intel NIC (measured with iperf3 and multiple parallel streams).
Is there anything else I could try or this is something I should actually expect from these cards ?
