https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280386 --- Comment #18 from [email protected] --- (In reply to Aleksandr Fedorov from comment #17) currently at default of dev.igb.0.fc=3 changing it has no apparent effect. however what i notice is that re-running the test results in some tests having 0 errors occur and others consistent errors, see below output from iperf3 with only 2 parallel tests (system has 4 cores): this test had no errors (see the "Retr" field): iperf3 -P2 -c 192.168.0.5 -t 600 Connecting to host 192.168.0.5, port 5201 [ 5] local 192.168.0.150 port 47836 connected to 192.168.0.5 port 5201 [ 7] local 192.168.0.150 port 12391 connected to 192.168.0.5 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 57.8 MBytes 484 Mbits/sec 0 2.00 MBytes [ 7] 0.00-1.00 sec 57.9 MBytes 485 Mbits/sec 0 2.00 MBytes [SUM] 0.00-1.00 sec 116 MBytes 969 Mbits/sec 0 - - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 1.00-2.00 sec 56.1 MBytes 471 Mbits/sec 0 2.00 MBytes [ 7] 1.00-2.00 sec 56.0 MBytes 470 Mbits/sec 0 2.00 MBytes [SUM] 1.00-2.00 sec 112 MBytes 941 Mbits/sec 0 - - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 2.00-3.00 sec 56.1 MBytes 471 Mbits/sec 0 2.00 MBytes [ 7] 2.00-3.00 sec 56.2 MBytes 472 Mbits/sec 0 2.00 MBytes [SUM] 2.00-3.00 sec 112 MBytes 943 Mbits/sec 0 - - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 3.00-4.00 sec 56.0 MBytes 470 Mbits/sec 0 2.00 MBytes [ 7] 3.00-4.00 sec 56.0 MBytes 470 Mbits/sec 0 2.00 MBytes [SUM] 3.00-4.00 sec 112 MBytes 940 Mbits/sec 0 ^C- - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 4.00-4.55 sec 30.6 MBytes 469 Mbits/sec 0 2.00 MBytes [ 7] 4.00-4.55 sec 30.8 MBytes 471 Mbits/sec 0 2.00 MBytes [SUM] 4.00-4.55 sec 61.4 MBytes 941 Mbits/sec 0 then if run again, it may experience errors, and if it does, the errors are consistently seen for the rest of the test run: iperf3 -P2 -c 192.168.0.5 -t 600 Connecting to host 192.168.0.5, port 5201 [ 5] local 192.168.0.150 port 60974 connected to 192.168.0.5 port 5201 [ 7] local 192.168.0.150 port 30555 connected to 192.168.0.5 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 48.5 MBytes 406 Mbits/sec 6 2.00 MBytes [ 7] 0.00-1.00 sec 67.0 MBytes 560 Mbits/sec 3 2.00 MBytes [SUM] 0.00-1.00 sec 116 MBytes 966 Mbits/sec 9 - - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 1.00-2.00 sec 52.5 MBytes 441 Mbits/sec 12 1.41 MBytes [ 7] 1.00-2.00 sec 59.5 MBytes 500 Mbits/sec 4 1.44 MBytes [SUM] 1.00-2.00 sec 112 MBytes 941 Mbits/sec 16 - - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 2.00-3.00 sec 58.5 MBytes 490 Mbits/sec 2 1011 KBytes [ 7] 2.00-3.00 sec 54.2 MBytes 454 Mbits/sec 3 510 KBytes [SUM] 2.00-3.00 sec 113 MBytes 944 Mbits/sec 5 - - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 3.00-4.00 sec 53.0 MBytes 445 Mbits/sec 3 2.00 MBytes [ 7] 3.00-4.00 sec 59.2 MBytes 497 Mbits/sec 3 168 KBytes [SUM] 3.00-4.00 sec 112 MBytes 942 Mbits/sec 6 ^C- - - - - - - - - - - - - - - - - - - - - - - - - [ 5] 4.00-4.64 sec 42.5 MBytes 559 Mbits/sec 2 338 KBytes [ 7] 4.00-4.64 sec 29.0 MBytes 381 Mbits/sec 1 2.00 MBytes [SUM] 4.00-4.64 sec 71.5 MBytes 941 Mbits/sec 3 the behaviour occurs independently of the dev.igb.0.fc value (3 or 0) -- You are receiving this mail because: You are the assignee for the bug.
