Hi Binghan, Please see section 6 of [0] for HW requirements and limitations of latency measurement in MoonGen (typically only a sub-set of packets can be measured for latency). IMO, this is a small compromise when considering an opensource solution for the test device.

Hi Binghan, Moongen does support collection of latency stats so it just needs to be added to VSPerf. We will add this as a JIRA ticket and advise you when its available. Thanks. -Christian, ________________________________ From: "Christian Trautman" <ctrau...@redhat.com<mailto:ctrau...@redhat.com>> To: "Binghan" <binghan...@gmail.com<mailto:binghan...@gmail.com>> Cc: opnfv-tech-discuss@lists.opnfv.org<mailto:opnfv-tech-discuss@lists.opnfv.org> Sent: Tuesday, August 30, 2016 9:14:40 PM Subject: Re: [opnfv-tech-discuss] [VSPERF] How to enable latency test? Hi Binghan, Moongen in VSPerf does not currently collect latency stats. I will inquire with the developers if this is planned in the near future and get back to you. -Christian, ________________________________ From: "Binghan" <binghan...@gmail.com<mailto:binghan...@gmail.com>> To: "MartinX Klozik" <martinx.klo...@intel.com<mailto:martinx.klo...@intel.com>> Cc: opnfv-tech-discuss@lists.opnfv.org<mailto:opnfv-tech-discuss@lists.opnfv.org> Sent: Tuesday, August 30, 2016 11:04:15 AM Subject: Re: [opnfv-tech-discuss] [VSPERF] How to enable latency test? Hi Martin, I am using Moongen, I cannot find latency result from Moongen log, I consider that VSperf parse Moongen log to get the test result. And about the configuration, I did not use the custom.conf, everything is by default. Sure, traffic generator part has been reconfigured, but nothing else. I attached pvp test log file and test report. Thanks a lot.

It would be good to check if these latencies are visible in traffic generator itself.

Hi VSPERF experts, I am trying to use VSPERF to benchmark OVS performance. I use default configuration, but no matter I run PVP test or P2P test, the latency result is always 0. Do I need to configure anything special to enable latency test?
