My main computer + unraid are on a 2.5G switch and both have 2.5GbE ports.
The unraid box has a realtek RTL8125 2.5GbE port on the motherboard, testing I would get full speed on 6.9.2 but after upgrading to 6.10.0 (and tested .1 + .2) the performance dropped.
iperf3 udp test:
unraid: iperf3 -s -p 5003 from windows machine, udp w/8 connections for 10 seconds: X:\iperf-3.1.3-win64> ./iperf3.exe -c 192.168.0.11 -p 5003 -P8 -t10 -i1 -b 3G -u
on 6.9.2 - 286 MBytes (2.40 Gbits/sec)
on 6.10.1 - 179 MBytes (1.50 Gbits/sec)
