Meeting summary
---------------

* Trevor Cooper  (trevor_intel, 15:00:36)
* Al Morton  (acm, 15:01:22)
* MS6 closes this week  (acm, 15:03:32)
* Martin, e-mail about lab, problem fixed  (acm, 15:04:59)
* Martin G. has some issue defining Line Rate, now solved due to old
  version  (acm, 15:05:38)
* TREX results are very low cf Ixia  (trevor_intel, 15:06:02)
* Thput numbers are lower than IXIA, may be due to number of cores, only
  able to reach 5Mil pps for small frames  (acm, 15:06:30)
* need to consider configurations, similar to Sridhar's performance
  during T-Gen Tests  (acm, 15:07:27)
* should result in a patch on Thursday.  (acm, 15:08:03)
* Al raised topic of T-gen limitations  (trevor_intel, 15:08:44)
* Seems like TREX does not have limitations for packet and stream
  creation  (trevor_intel, 15:09:07)
* Propose looking at generator config files to compare - Sridhar will
  send out details and config files. Had to use TREX GUI for test setup
  (manual setup)  (trevor_intel, 15:11:22)
* ACTION: Sridhar: make configs avaliable, in JIRA  (acm, 15:14:15)
* Test API  (trevor_intel, 15:18:40)
  * result DB treats all throughput tests (over different packet sizes)
    as one test, Martin revised start and stop times  (acm, 15:20:23)
  * ACTION: marst please review martin's patch  (acm, 15:20:46)
  * Mars already +1, "beautiful patch"  (acm, 15:21:20)
  * Morgan has asked for completion date, Mars says tested in 12 hours,
    so probably donetomorrow.  (acm, 15:23:33)
  * min max and average come from T-gen once per second  (acm, 15:26:21)
  * tests are running on Spirent Lab, can run on Intel pod, but with
    VMs?  yes, traffic gen load level and other? issues...  (acm,
    15:30:13)
  * trevor_intel  how can we actually use any of these results?  (acm,
    15:30:47)
  * Sridhar - we can get the same histogram from T-Rex, but need patch.
    and need patch from IXIA...  (acm, 15:32:32)
  * Sridhar is showing both live collection, and Histogram for results
    at end of test  (acm, 15:33:15)
  * Spirent VMs on Intel Pod need NTP for delay to work properly  (acm,
    15:33:55)
  * Martin - 40% of Sridhar's patch is re-usable for other T-gens.
    (acm, 15:34:35)
  * some discussion of collectd and IPFIX to gather Live data during the
    testing  (acm, 15:36:42)
  * #info  for future: run multiple collectors at the same time (as
    above)  (acm, 15:37:37)
  * Sridhar has a patch to examine collectd simple stats on CPU, OVS,
    etc. then prepare plots (as acm suggested on e-mail)  (acm,
    15:39:02)
  * trevor_intel  do we want to commit to this in E-release? there seems
    to be risk, so do not submit now, it was not announced for E  (acm,
    15:40:04)
  * Martin agrees  (acm, 15:40:29)
  * VSPERF-527 is the Story for this.  We can close Noisy Neighbor
    tickets VSPERF 524 and 523  (acm, 15:42:21)
  * plan is to deprecate artifacts directory (?)  (acm, 15:43:26)
  * Christian not here, but any progress? nothing else tested.  (acm,
    15:44:52)
  * SRIOV tests in CI are low, compared to P2P  (acm, 15:48:22)
  * Martin has produced higher results, but not with zero packet loss
    (acm, 15:48:49)
  * one VM running with SR-IOV, seems to exceed PCI bus limitations
    (acm, 15:49:46)
  * SR-IOV configures two interfaces (virtual?) per one? interface card
    (acm, 15:52:33)
  * logical ports on OVS may be limiting factor  (acm, 15:53:53)
  * Martin  current SR-IOV may be the limitation of VM with single
    physical core  (acm, 15:54:27)
  * VSPERF-519  should have documentation related to this and *all* new
    test cases?  (acm, 15:56:53)
  * we are way behind on documentation for E-release, within the next 3
    weeks.  (acm, 15:57:46)
  * minimum we can do is to get the list of test cases that are
    currently implemented  (acm, 15:59:56)
  * not active now, for future, not for E-release  (acm, 16:00:49)



Meeting ended at 16:01:18 UTC.
