Hi, I am using iperf-2.0.5 to measure UDP throughput on a 10 Gbps link, however test results do not go above 4.99 Gbps. When using TCP however the test shows 9.90 Gbps.
Has anyone been able to operate iperf with UDP above 5 Gbps? Thanks, Jimmy jimmy@jbraid2:~/old/iperf-2.0.5/src$ ./iperf -u -c 192.168.10.101 -w 16M -b 10000m -l 8972 ------------------------------------------------------------ Client connecting to 192.168.10.101, UDP port 5001 Sending 8972 byte datagrams UDP buffer size: 32.0 MByte (WARNING: requested 16.0 MByte) ------------------------------------------------------------ [ 3] local 192.168.10.103 port 42070 connected with 192.168.10.101 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 5.81 GBytes 4.99 Gbits/sec [ 3] Sent 695918 datagrams [ 3] Server Report: [ 3] 0.0-10.0 sec 5.81 GBytes 4.98 Gbits/sec 0.814 ms 0/695917 (0%) [ 3] 0.0-10.0 sec 1 datagrams received out-of-order jimmy@jbraid2:~/old/iperf-2.0.5/src$ ./iperf -w 16M -c 192.168.10.101 ------------------------------------------------------------ Client connecting to 192.168.10.101, TCP port 5001 TCP window size: 32.0 MByte (WARNING: requested 16.0 MByte) ------------------------------------------------------------ [ 3] local 192.168.10.103 port 48529 connected with 192.168.10.101 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 11.5 GBytes 9.90 Gbits/sec ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2d-c2 _______________________________________________ Iperf-users mailing list Iperf-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/iperf-users
