Re: [Openstack-operators] OpenStack Tuning Guide
Yep, I 100% agree, and that's my goal. Gather up everyone's info and best practices, and then work on distilling it into a new chapter (or perhaps even a whole new section) of the operators or administration guide.

Re: [Openstack-operators] OpenStack Tuning Guide
Hello there, Very interesting initiative ! I'm currently working on the performance side too on our (french astrophysics cloud) OpenStack deployment but to say so currently I'm just following what CERN did regarding to Nova/CPU configuration. It's essentially around KSM, NUMA, CPU pinning, EPT and performance measures are compared through Spec 06 benchmarks, which is standard for HPC/HTC computing. You can take a look at the very interesting blog from CERN here http://openstack-in-production.blogspot.fr/ and if you want I have few slides from various meetings like HEPIX on these subjects.

Re: [Openstack-operators] OpenStack Tuning Guide
The official documentation would greatly benefit from more practical information such as tuning... most likely in the administration or operations guide, at least for now. Ideally, I would like to see a operators contribute documentation for complete production deployments that others can use as a reference for new deployments and avoid reinventing the wheel.
