Hi @dezza. That's weird. Do you perhaps run IDS/IPS? I don't but even with the hardware offloading disabled, I get full line-rate (I use these same tunabels on a 6x i226 N100 unit from Topton). I determined these tunables using the documentation of both OPNsense and pfSense, but also some other sources. Unfortunately I did not wrote down those sources.
