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.
Following the etherpad !
Regards,

Awesome start. Rabbit fd tweaks are the bane of every install...including some
of my own...

Hey all!
Something that jumped out at me in Tokyo was how much it seemed that "basic" tuning stuff
wasn't common knowledge. This was especially prevalent in the couple of rabbit talks I went to. So,
in order to pool our resources, I started an Etherpad titled the "OpenStack Tuning Guide"
(https://etherpad.openstack.org/p/OpenStack_Tuning_Guide). Eventually I expect this should go into
the documentation project, and much of it may already exist in the operators manual (or elsewhere),
but I thought that getting us all together to drop in our hints, tweaks, and best practices for
tuning our systems to run OpenStack well, in real production, would be time well spent.
It's a work in progress at the moment, and we've only just started, but please
feel free to check it out. Feedback and community involvement is super welcome,
so please don't hesitate to modify it as you see fit.
Finally, I hate diverging resources, so if something like this already exists
please speak up so we can focus our efforts on making sure that's up to date
and well publicized.
Thanks everyone!
-- Kevin
