Re: [Openstack] {Disarmed} Re: {Disarmed} Re: EC2-API in Ocata - Help wanted

[Anastasia Kravets]

Hi Georgios,

The difference was caused by the presence of caching metadata in nova and the 
lack of caching in ec2-api.
We’ve fixed it in ec2-api in master.

Thank you for your assistance.
Regards,
Anastasia

Hi, 

No sorry but we haven’t run this with os-profiler (and don’t have plans to run).

Thank you,
Anastasia

[openstack-dev] [nova] Degradation of performance on master

[Anastasia Kravets]

Hi all,

Making some investigations in our project, we have run rally tests, and have 
noticed degradation of performance of nova on master compared with ocata 
branch. 
`nova list` on ocata branch with 100 servers run in 1,6s while the `nova list` 
on master branch with 40 servers only run in 1,8s.
Nova is configured to use fake libvirt.

Pay your attention. Thank you.

Best Regards,
Anastasia Kravets

[openstack-dev] [chef] ec2-api cookbook

[Anastasia Kravets]

Hi, team!

If you remember, we've created a cookbook for ec2-api service. After last 
discussion I’ve refactored it, have added specs.
The final version is located on cloudscaling github: 
https://github.com/cloudscaling/cookbook-openstack-ec2.
How do we proceed to integrate our cookbook to your project?

Regards,
Anastasia
