Hello, I have 2 boxes with FreeBSD 10.1-RELEASE/amd64 and "Intel(R) PRO/1000 Network Connection 7.4.2" NIC's directly connected to each other. I noticed strange problem - I'm loosing small UDP packets under high load. I've tried to test it with iperf and got the following:
--- vd@v0s4:~ % iperf3 -u -c 1.2.3.4 Connecting to host 1.2.3.4, port 5201 [ 4] local 1.2.3.3 port 64254 connected to 1.2.3.4 port 5201 [ ID] Interval Transfer Bandwidth Total Datagrams [ 4] 0.00-1.01 sec 120 KBytes 976 Kbits/sec 15 [ 4] 1.01-2.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 2.01-3.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 3.01-4.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 4.01-5.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 5.01-6.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 6.01-7.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 7.01-8.00 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 8.00-9.01 sec 128 KBytes 1.05 Mbits/sec 16 [ 4] 9.01-10.01 sec 128 KBytes 1.05 Mbits/sec 16 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 4] 0.00-10.01 sec 1.24 MBytes 1.04 Mbits/sec 0.325 ms 0/159 (0%) [ 4] Sent 159 datagrams Any advice how to solve it ?
