I did a few different tests, ensuring a solid 950~ Mbit/s link during my ip= erf3 tests. Each of them raised error when using the FreeBSD box as the iperf3 client. For 60 seconds each as you did, I tested though with iperf3 -P4: bridge123 1500 58:9c:fc:10:ff:92 624390 0 0=20 4886859 13 0 iperf -P8 bridge123 1500 58:9c:fc:10:ff:92 1262380 0 0=20 9777020 187 0 bridge123 - 192.168.88.0/24 192.168.88.3 1216769 - -=20 9777104 - - and iperf3 -P40, which is as many threads as I have physically: bridge123 1500 58:9c:fc:10:ff:92 2179910 0 0=20 14681352 1756 0 bridge123 - 192.168.88.0/24 192.168.88.3 2134298 - -=20 14683001 - - The Oerrs field increases in error significantly, but if you notice, differ= ent P values do not seem to change the rate of errors generated either.
