=== Addition Info === ---- * '''Iperf client only runs one thread'''. To get a better ''real world'' result, set the client to run with more threads. This can be used in UDP or TCP mode. As you notice above, I was only able to achieve 815mbps with udp testing. Enable 20 threads at 100mbps, I can now achieve 954mpbs. <source lang=bash enclose=div> ## set 10 threads #] iperf -c 10.69.1.250 -P 10 # iperf -u -c 10.69.1.254 -t 10 -b 100M -P 20 ------------------------------------------------------------ Client connecting to 10.69.1.254, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 224 KByte (default) ------------------------------------------------------------ [ 22] local 10.69.1.250 port 54270 connected with 10.69.1.254 port 5001 [ 3] local 10.69.1.250 port 43703 connected with 10.69.1.254 port 5001 [ 6] local 10.69.1.250 port 41342 connected with 10.69.1.254 port 5001 [ 5] local 10.69.1.250 port 47863 connected with 10.69.1.254 port 5001 [ 4] local 10.69.1.250 port 45683 connected with 10.69.1.254 port 5001 [ 7] local 10.69.1.250 port 53533 connected with 10.69.1.254 port 5001 [ 10] local 10.69.1.250 port 58435 connected with 10.69.1.254 port 5001 [ 8] local 10.69.1.250 port 34540 connected with 10.69.1.254 port 5001 [ 9] local 10.69.1.250 port 51102 connected with 10.69.1.254 port 5001 [ 11] local 10.69.1.250 port 52498 connected with 10.69.1.254 port 5001 [ 12] local 10.69.1.250 port 42381 connected with 10.69.1.254 port 5001 [ 15] local 10.69.1.250 port 57701 connected with 10.69.1.254 port 5001 [ 13] local 10.69.1.250 port 60505 connected with 10.69.1.254 port 5001 [ 14] local 10.69.1.250 port 33364 connected with 10.69.1.254 port 5001 [ 16] local 10.69.1.250 port 36105 connected with 10.69.1.254 port 5001 [ 17] local 10.69.1.250 port 37829 connected with 10.69.1.254 port 5001 [ 18] local 10.69.1.250 port 43117 connected with 10.69.1.254 port 5001 [ 19] local 10.69.1.250 port 54920 connected with 10.69.1.254 port 5001 [ 20] local 10.69.1.250 port 38253 connected with 10.69.1.254 port 5001 [ 21] local 10.69.1.250 port 48120 connected with 10.69.1.254 port 5001 [ ID] Interval Transfer Bandwidth [ 6] 0.0-10.0 sec 56.9 MBytes 47.7 Mbits/sec [ 6] Sent 40575 datagrams [ 9] 0.0-10.0 sec 57.0 MBytes 47.8 Mbits/sec [ 9] Sent 40672 datagrams [ 15] 0.0-10.0 sec 57.1 MBytes 47.9 Mbits/sec [ 15] Sent 40729 datagrams [ 14] 0.0-10.0 sec 56.8 MBytes 47.7 Mbits/sec [ 14] Sent 40550 datagrams [ 17] 0.0-10.0 sec 57.1 MBytes 47.9 Mbits/sec [ 17] Sent 40730 datagrams [ 19] 0.0-10.0 sec 56.9 MBytes 47.8 Mbits/sec [ 19] Sent 40618 datagrams [ 20] 0.0-10.0 sec 56.7 MBytes 47.6 Mbits/sec [ 20] Sent 40457 datagrams [ 5] 0.0-10.0 sec 57.1 MBytes 47.8 Mbits/sec [ 5] Sent 40695 datagrams [ 4] 0.0-10.0 sec 57.1 MBytes 47.9 Mbits/sec [ 4] Sent 40750 datagrams [ 10] 0.0-10.0 sec 57.1 MBytes 47.8 Mbits/sec [ 10] Sent 40724 datagrams [ 18] 0.0-10.0 sec 56.9 MBytes 47.7 Mbits/sec [ 18] Sent 40570 datagrams [ 21] 0.0-10.0 sec 57.0 MBytes 47.8 Mbits/sec [ 21] Sent 40680 datagrams [ 22] 0.0-10.0 sec 57.0 MBytes 47.7 Mbits/sec [ 22] Sent 40653 datagrams [ 3] 0.0-10.0 sec 57.0 MBytes 47.7 Mbits/sec [ 3] Sent 40638 datagrams [ 7] 0.0-10.0 sec 57.0 MBytes 47.7 Mbits/sec [ 7] Sent 40627 datagrams [ 8] 0.0-10.0 sec 56.9 MBytes 47.7 Mbits/sec [ 8] Sent 40622 datagrams [ 11] 0.0-10.0 sec 57.0 MBytes 47.7 Mbits/sec [ 11] Sent 40651 datagrams [ 12] 0.0-10.0 sec 57.1 MBytes 47.9 Mbits/sec [ 12] Sent 40766 datagrams [ 13] 0.0-10.0 sec 56.9 MBytes 47.6 Mbits/sec [ 13] Sent 40571 datagrams [ 16] 0.0-10.0 sec 56.9 MBytes 47.7 Mbits/sec [ 16] Sent 40595 datagrams [SUM] 0.0-10.0 sec 1.11 GBytes 954 Mbits/sec </source> [[Category:Linux]] [[Category:Networking]] [[Category:Performance]]
