Poor performance on igb driver

If we aren't talking about forwarding, but a client-server speed test, I can confirm igb does Gigabit fairly easy.
I just setup a spare port to test without forwarding, VLANs, firewall rules or netmap. Test done with iperf3, pfSense as server and I get an average of 936Mbits/sec both ways (-c -R).
hw.igb.max_interrupt_rate="16000" hw.igb.rx_process_limit="-1" hw.igb.tx_process_limit="-1" hw.intr_storm_threshold="10000" net.link.ifqmaxlen="2048"
dev.igb.0.eee_disabled 1 net.inet.tcp.hostcache.enable 0 - use this for tests only

@stephenw10 Did quite a bit of research with settings, tweaking them over and over again. Also installed other firewall/router OS distributions to isolate whether the problem was with PFSense itself, or is a hardware limitation on these boxes.
Long story short - I can safely say the Qotom J1900 cannot pass gigabit down/up in a practical, real world situation. The bottleneck isn't the CPU, but the PCIe lanes.
Having said that, I've no real practical application of a Gigabit up/down connection today - so putting this on the backburner and living with whatever >500mbps I'm getting, until I decide to upgrade this box.
