https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D280386 --- Comment #10 from fatalnix@gmail.com --- I have upgraded to 14.1-release-p2 and I am now able to reproduce this issue using the same tests. 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 <Link#18> 58:9c:fc:10:ff:92 624390 0 0=20 4886859 13 0 iperf -P8 bridge123 1500 <Link#18> 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 <Link#18> 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. Checking with sysctl after: # sysctl dev.igb.0.iflib | grep r_drops dev.igb.0.iflib.txq7.r_drops: 94 dev.igb.0.iflib.txq6.r_drops: 291 dev.igb.0.iflib.txq5.r_drops: 52 dev.igb.0.iflib.txq4.r_drops: 356 dev.igb.0.iflib.txq3.r_drops: 232 dev.igb.0.iflib.txq2.r_drops: 252 dev.igb.0.iflib.txq1.r_drops: 311 dev.igb.0.iflib.txq0.r_drops: 157 This stayed at 0 yesterday when I was still running on 14.0 release p6. --=20 You are receiving this mail because: You are the assignee for the bug.=
