openstack | The meeting name has been set to 'neutron_performance' | 16:01 |
njohnston_ | o/ | 16:01 |
rubasov | o/ | 16:01 |
mlavalle | hey guys | 16:02 |
mlavalle | rubasov: when are you arriving to Berlin? | 16:02 |
rubasov | mlavalle: monday early afternoon | 16:02 |
*** dklyle has joined #openstack-meeting | 16:02 | |
rubasov | mlavalle: the same plane as gibi | 16:02 |
mlavalle | I'll be there since Friday morning. I'm attending the edge computing hackathon | 16:03 |
mlavalle | during the weekend | 16:03 |
rubasov | mlavalle: sounds interesting | 16:03 |
bcafarel | this time it's not my fault holding the others from being there :) | 16:04 |
mlavalle | bcafarel: duly noted | 16:04 |
mlavalle | LOL | 16:04 |
mlavalle | let's wait one more minute | 16:04 |
mlavalle | for slaweq | 16:04 |
mlavalle | ok, let's get started | 16:05 |
mlavalle | #topic last week's action items | 16:06 |

mlavalle | First rubasov to add top request offenders to rally job | 16:06 |
*** cloudrancher has joined #openstack-meeting | 16:06 | |
rubasov | I'm sorry to report but I didn't make much progress | 16:07 |
*** _alastor1 has joined #openstack-meeting | 16:07 | |
rubasov | started to learn about rally | 16:07 |
rubasov | but then got busy with other stuff | 16:07 |
mlavalle | yeah, I imagine | 16:07 |
mlavalle | the demo, maybe? | 16:07 |
rubasov | yep | 16:07 |
mlavalle | np | 16:07 |
slaweq | hi | 16:07 |
rubasov | but I still have it on my todo list | 16:07 |
slaweq | sorry for being late | 16:07 |
rubasov | so I will get to it at some point | 16:08 |
mlavalle | let's move that action item for the next meeting | 16:08 |
mlavalle | #action rubasov to add top request offenders to rally job | 16:08 |
mlavalle | next one is slaweq to create a experimental rally job with osprofiler enabled | 16:09 |
slaweq | so, I proposed patch for rally https://review.openstack.org/#/c/615340/ | 16:09 |
slaweq | and then I have WIP patch which depends on it: https://review.openstack.org/#/c/615350/ | 16:09 |
slaweq | it basically works, and I can see trace id in rally result | 16:10 |
slaweq | but now I need to copy somehow redis db to job result files | 16:10 |
slaweq | so I will continue work on this in next days | 16:10 |
mlavalle | Great progress slaweq. Thanks | 16:11 |
mlavalle | next action item was mlavalle to simplify the DB traces | 16:12 |
mlavalle | I just proposed this patch https://review.openstack.org/#/c/615585 | 16:12 |
mlavalle | I made sure that the code that I am removing is the only one in Neutron that add traces for SQLAlchemy | 16:13 |
*** ttsiouts has quit IRC | 16:14 | |
mlavalle | so after this one merges, we should get much cleaner reports | 16:14 |
mlavalle | with less duplicate information | 16:14 |
mlavalle | which will make the reports easier to analyze | 16:14 |
*** ttsiouts has joined #openstack-meeting | 16:14 | |
mlavalle | ok | 16:14 |
mlavalle | that's it for action items | 16:14 |
mlavalle | #topic On demand agenda | 16:15 |
*** openstack changes topic to "On demand agenda (Meeting topic: neutron_performance)" | 16:15 | |
njohnston_ | I just wanted to note that the ipam work I have been doing has some promising speed results | 16:15 |
mlavalle | how so? | 16:15 |
*** imacdonn has quit IRC | 16:16 | |
*** imacdonn has joined #openstack-meeting | 16:17 | |
njohnston_ | https://review.openstack.org/#/c/592164/ look at my last comment | 16:17 |
njohnston_ | the rally task "Action neutron.create_port (x50)" looks like it is ~30% faster | 16:17 |
mlavalle | wow, nice! | 16:18 |
mlavalle | should we add some profiling calls to the IPAM code? | 16:18 |
njohnston_ | This is mostly accomplished by taking the code in ipam to try to randomly select new IPs (to avoid contention) and replacing it with random.sample | 16:18 |
*** ttsiouts has quit IRC | 16:19 | |
njohnston_ | mlavalle: We could, although I think we may have wrung all the speed gains we can out of this code. But I'm definitely open to adding profiling to confirm it. :-) | 16:19 |
mlavalle | mhhhh, no, if you don't see it evidently worthwhile at this point, let's wait until we can see results from the rally jobs | 16:20 |
mlavalle | with more data, we may conclude that further investigation is warranted | 16:21 |
mlavalle | but at this point I think we are still "shooting in the dark" | 16:21 |
mlavalle | but I think this work will definitely have impact | 16:22 |
mlavalle | becuase port creation is among the top offenders | 16:22 |
mlavalle | which this work with IPAM impacts | 16:22 |
mlavalle | great job, njohnston_ | 16:23 |
njohnston_ | I agree - and I want to thank tidwellr and Roman (I don;t know his IRC) for great review feedback | 16:23 |
njohnston_ | would not have happened without them | 16:23 |
slaweq | njohnston_: Roman's nic is gryf :) | 16:24 |
njohnston_ | Ah thanks :-) | 16:24 |
mlavalle | yeah, tidwellr did a lot of work in IPAM code a couple of yeards ago | 16:24 |
mlavalle | and gryf was probably with John Bellamaric's group | 16:25 |
mlavalle | and they also did great work in IPAM | 16:25 |
mlavalle | ok, let's move on | 16:26 |
mlavalle | I think that at this point what we need is data | 16:26 |
mlavalle | to start gleaning insight | 16:26 |
mlavalle | and to get to that point we need to finish our action items | 16:26 |
mlavalle | do we agree? | 16:26 |
njohnston_ | +1 | 16:27 |
slaweq | +1 | 16:27 |
mlavalle | so let's focus on concluding our action items | 16:27 |
rubasov | yep | 16:27 |
mlavalle | and we can re-take the discussion next meeting | 16:27 |
mlavalle | ok? | 16:27 |
njohnston_ | sounds like a plan! | 16:27 |
slaweq | ok for me :) | 16:27 |
mlavalle | ok, guys, thanks for attending | 16:28 |
rubasov | thank you guys | 16:28 |
njohnston_ | thanks all | 16:28 |
