Signed-off-by: Amos Kong<[email protected]> ---Hi Amos, Seems the Windows guest netperf cases is useing 2.4.5 exe files for the netperf_exe. So the performance tests for windows may still using netperf 2.4.5 which may cause the results not comparable with Linux results. So cc this change to wenli.Hi Yiqiao, I thought you use cygwin to compile and run netperf in Windows, and I only tested Linux guest. We can make it configurable, and still use 2.4.5 for Windows guests. Or update netperf program used for Windows guests. I'm working on the demo mode, it needs some change of netperf case. I will try to finish it with linux guest first.Akong, Did you try your patch before you send it out ?Sure. The following result is unstable, even uncorrect, but netperf-2.6 works with current parameters.# cat ../../results/default/virt.kvm.virtio_blk.smp2.virtio_net.RHEL.6.3.x86_64.netperf.host_guest/results/netperf-result.1355461197.02.RHS### kvm-userspace-ver : qemu-kvm-0.12.1.2-2.337.el6.x86_64 ### guest-kernel-ver : 2.6.32-262.el6.x86_64 ### kvm_version : 2.6.32-343.el6.x86_64 ### session-length : 50 Category:TCP_STREAM (RX)size| sessions| throughput| CPU| thr_per_CPU| rx_pkts| tx_pkts| rx_byts| tx_byts| re_pkts| rx_intr| tx_intr| io_exit| irq_inj|tpkt_per_exit|rpkt_per_irq 512| 4| 5392.59| 59.09| 91.26| 832495| 339588| 49657066176| 22426890| 0| 330773| 5| 242963| 404617| 2.06| 1.40 512| 16| 5507.38| 58.93| 93.46| 948749| 413731| 50095299758| 28013684| 0| 348580| 348| 92530| 418111| 2.27| 4.47 512| 64| 5919.49| 62.34| 94.95| 1111896| 884332| 45020654734| 61852978| 0| 493078| 2323| 42263| 560081| 1.99| 20.92Category:TCP_MAERTS (TX)size| sessions| throughput| CPU| thr_per_CPU| rx_pkts| tx_pkts| rx_byts| tx_byts| re_pkts| rx_intr| tx_intr| io_exit| irq_inj|tpkt_per_exit|rpkt_per_irq 512| 4| 6248.29| 66.25| 94.31| 3106493| 3436855| 204766536| 57534865974| 0| 16808| 12865| 6392| 86463| 35.93| 537.68 512| 16| 6698.82| 64.91| 103.20| 2033257| 2290066| 133839576| 57816962454| 37| 4105| 4510| 20080| 81010| 25.10| 114.05 512| 64| 7159.50| 59.30| 120.73| 969372| 1161921| 63548412| 34647179394| 1081| 1611| 2106| 10245| 47184| 20.54| 113.41Category:TCP_RRsize| sessions| trans.rate| CPU| thr_per_CPU| rx_pkts| tx_pkts| rx_byts| tx_byts| re_pkts| rx_intr| tx_intr| io_exit| irq_inj|tpkt_per_exit|rpkt_per_irq 512| 32| 36867.86| 53.61| 687.70| 2711570| 2710621| 1566236464| 1565794136| 0| 1020381| 41| 1051694| 1100593| 2.46| 2.58 512| 128| 44619.06| 62.53| 713.56| 3097148| 3095450| 1788280186| 1787460842| 0| 39050| 47| 32362| 119253| 25.97| 95.65netperf does not support "-t TCP_MAERTS -- -m $message" in 2.6.0 version.Netperf could not work correctly with "TCP_MAERTS -- -m $message" parameters, The bytes of "Send Message" already keep 16384 bytes no matter what "-m " specify.[root@dhcp-8-167 virt]# /tmp/netperf-2.6.0/src/netperf -V Netperf version 2.6.0[root@dhcp-8-167 virt]# /tmp/netperf-2.6.0/src/netperf -D 1 -H 192.168.58.23 -l 10 -C -c -t TCP_MAERTS -- -m 512 (this cmdline is got from Autotest log) MIGRATED TCP MAERTS TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.58.23 () port 0 AF_INET : demo Interim result: 5242.37 10^6bits/s over 1.143 seconds ending at 1355463157.493 Interim result: 4844.63 10^6bits/s over 1.082 seconds ending at 1355463158.575 Interim result: 5163.48 10^6bits/s over 1.001 seconds ending at 1355463159.576 Interim result: 5234.31 10^6bits/s over 1.001 seconds ending at 1355463160.577 Interim result: 5035.61 10^6bits/s over 1.040 seconds ending at 1355463161.616 Interim result: 5284.55 10^6bits/s over 1.002 seconds ending at 1355463162.619 Interim result: 5314.73 10^6bits/s over 1.000 seconds ending at 1355463163.619 Interim result: 5160.96 10^6bits/s over 1.030 seconds ending at 1355463164.649 Interim result: 5057.84 10^6bits/s over 1.020 seconds ending at 1355463165.669 Interim result: 5103.19 10^6bits/s over 0.681 seconds ending at 1355463166.351Recv Send Send Utilization Service Demand Socket Socket Message Elapsed Recv Send Recv Send Size Size Size Time Throughput local remote local remote bytes bytes bytes secs. 10^6bits/s % S % S us/KB us/KB 87380 16384 512 10.00 5143.63 62.02 33.24 3.951 1.059The result shows that "-t TCP_MAERTS -- -m 256" parameter works well with netperf-2.6.0# ./src/netperf -l 60 -H 192.168.100.16 -t TCP_MAERTS -C -c -- -m 32 in netserver side, # strace -p `pgrep netserver`sendto(10, "netperf\0netperf\0netperf\0netperf\0"..., 16384, 0, NULL, 0) = 16384 sendto(10, "netperf\0netperf\0netperf\0netperf\0"..., 16384, 0, NULL, 0) = 16384 sendto(10, "netperf\0netperf\0netperf\0netperf\0"..., 16384, 0, NULL, 0) = 16384
Hi Rick, I notice that the -- -m does not work well with TCP_MAERTS in netperf 2.6.0, please see the above discussion and could you please help us to check this?
Thanks
