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.
