I managed to install FreeBSD 14.0-RELEASE-p3 on it, and both Ethernet devices (genet0 and ue0) were properly identified. However, network throughput on my gigabit network is pretty bad; iperf3 reports a maximum transfer speed of 291 Mbits/sec. Flashing OpenWRT on the same hardware using the same ethernet port, I'm able to achieve 923 Mbits/sec. > > Does anyone have any suggestions on how to improve throughput under FreeBSD? > > Thank you > Steve I just tested with an RPi4 (4 GB) and 14.0 using iperf3. It looks like I'm getting a rather variable number of retransmissions. On my first run (client on RPi 4), I got 460 Mb/s with a lot of retransmissions, but the next couple of runs, including one receiving, I got about 940 Mb even with some retransmissions. The peers were fairly fast FreeBSD 13.2 and 15-current systems. Are you seeing retransmissions? I'll try to look into this, but I'm not sure when I'll get to it. Mike
