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

* Al Morton  (acm, 15:04:13)
* Al plans to attend the plugfest, Sridhar plans to decide this week
  (acm, 15:05:13)
* no questions on milestones  (acm, 15:08:50)
* Add multistream support to T-Rex  (acm, 15:10:41)
  * Christian has made a recent update, Martin will look over tomorrow
    (acm, 15:11:10)
  * Sridhar has tried the tests, p2p tests seem to show default at 64
    streams  (acm, 15:11:52)
  * 03 traffic conf file may need multistream truned off, christian
    replied  (acm, 15:12:57)
  * L2 Src-only L3 is soruce only, L4 Source only, linear address
    rotation for now.  (acm, 15:14:44)
  * Sridhar, how to enable Latency measurements?  Martin - should be
    VSperf config, 03_traffic.conf  (acm, 15:16:21)
  * default is 1000 pps  (acm, 15:17:38)

* Status of tuning CI configuration (Martin)  (acm, 15:18:01)
  * no progress yet, but daily job is running again, results are
    fluctuating, p2p and pvp results,  (acm, 15:19:33)
  * ACTION: anyone to look into this variation in the results,  (acm,
    15:20:11)
  * intel firewall issue has not been resolved, this is a work-around...
    (acm, 15:21:10)
  * failures of teh verify jobs are out of our control, seems to be a
    race condition among shared jobs at those machines.  (acm, 15:22:18)
  * but problem observed since September, re-boot of the shared server
    fixed for a while.  (acm, 15:23:12)
  * possible work-around is to ask to move our job to another physical
    server which is not so busy  (acm, 15:25:24)
  * Martin has the admin contacts, was Fatih, now another...  (acm,
    15:26:49)

*   (acm, 15:27:56)

* Discuss VPP test cases and results in CSIT report  (acm, 15:28:04)
  *
    https://docs.fd.io/csit/rls1707/report/vpp_performance_tests/overview.html
    (acm, 15:28:52)
  * main difference is packet sizes, FDIO CSIT uses IMIX, small and
    large and Jumbo packet sizes  (acm, 15:34:17)
  * Need some generic API for control, IMIX Genome was proposed.  (acm,
    15:35:58)
  * there is a JIRA ticket for this, also for multistream a common
    definition of fields to manipulate (Wireshark) VSPERF-520 I think
    (acm, 15:38:20)
  * Sridhar - will take a look at the specifications, in 2 weeks will
    summarize study, for IMIX specifications  (acm, 15:41:11)
  * CSIT CPU tuning, not much surprising (acm and Martin), we are using
    Christian's Tuned recommendation,  (acm, 15:45:15)
  * trade-off betwen tuning complexity and final results.  (acm,
    15:45:38)
  * looked at some ETH throughput, seems consistent but with many
    variables in test codes to understnad further  (acm, 15:58:06)
  * also, at 64 byte frames, the linmitation is the NIC (Niantic)  (acm,
    15:58:35)
  * ACTION: the CSIT comparison could prompt new features for F release,
    everyone to take a look and consider resources needed  (acm,
    16:00:00)
  * Sridhar will be on holiday next week  (acm, 16:01:44)



Meeting ended at 16:01:55 UTC.
