| DinaBelova | Folks, I'm really sick today... I'd love to cancel todays meeting... | 12:27 |
|---|---|---|
| DinaBelova | will send an email to openstack-dev and openstack-operators | 12:27 |
| *** hkominos has joined #openstack-performance | 12:40 | |
| hkominos | Hello Openstackers. I have a quick question if you dont mind. How much whould you think that running openstack nova (and the other services ) costs in terms of CPU in the compute host? I mean a Server with just an OS how much faster would that system be? | 12:41 |
| DinaBelova | hkominos hey! | 13:55 |
| hkominos | hello | 13:56 |
| DinaBelova | we're having Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz on our lab computes | 13:56 |
| DinaBelova | and when nothing is happening it seems like CPU is not almost used at all | 13:57 |
| DinaBelova | https://drive.google.com/file/d/0ByRtVrZu5ifzc0FKUzlHX2MzNk0/view?usp=sharing | 13:57 |
| hkominos | you mean just by having openstack services running? | 13:57 |
| DinaBelova | yes, only OpenStack services and that's it | 13:58 |
| DinaBelova | when we're not running any tests | 13:58 |
| DinaBelova | I do not have screenshots of the situation during the load | 13:58 |
| hkominos | It looks reasonable. However I am now conducting an experiment. I am running a workload on a COmpute host (part of fuel) and then on the same machine as a BM machine with ironic and i am seeing a 15% difference | 13:59 |
| DinaBelova | but neutron agents may eat something when DVR is used | 13:59 |
| DinaBelova | it's interesting | 13:59 |
| DinaBelova | are all other topologies identical? | 13:59 |
| hkominos | very itneresting | 13:59 |
| hkominos | all other variables yes | 13:59 |
| DinaBelova | only hypervisor is different? | 13:59 |
| DinaBelova | interesting.. | 13:59 |
| hkominos | speaking of which | 14:00 |
| hkominos | I am running ton the compute host | 14:00 |
| hkominos | not in a VM | 14:00 |
| hkominos | So in the BM machine KVM is not even installed i think | 14:00 |
| hkominos | I dont think that it would matter so much though | 14:00 |
| hkominos | So It could be that you are seeing your system idling because all the "load" from checking the task qeues etc is spread in many cpus and therefore not visible and only when all cpus go at 100% it becomes more obious. I dont know to be honest | 14:02 |
| *** permalac has quit IRC | 14:14 | |
| DinaBelova | hkominos we'll check the same monitoring screen once tests will be running | 14:25 |
| DinaBelova | let's see how it'll hehave | 14:25 |
| DinaBelova | Folks, one more reminder - no meeting today. I need to go to hospital due to feeling really bad | 14:36 |
