based on your last comment I am going to close this bug as it is not
"reproducible".
Please feel free to re-open it if you have a clear way to reproduce it again.
Thanks

Title:
nova-api performance issues on "openstack server list"
Status in OpenStack Compute (nova):
Invalid
Bug description:
Relevant information TL;DR:
RDO stable Mitaka deployed with OpenStack puppet modules.
Keystone with fernet tokens, Nova with keystone_authtoken memcached caching
set (also reproduced with sql tokens and nova without memcached caching for
authtoken). nova-api is handled behind apache with mod wsgi.
Problem TL;DR:
In an empty new deployment on bare metal (no images, no virtual machines,
etc.), "openstack server list" will intermittently take >5 seconds (up to ~10)
to return. The only noticeable thing that happens when "openstack server list"
is slow is that the logs will be plastered with a bunch of
"_create_extension_schema", "_rebuild_extension_schema", "_register_resources"
and so on.
All other installed projects (glance, keystone, neutron) return command
output consistently under 2 seconds.
