Subject: [Openstack] Call to API very slow [Grizzly]
All operations in my Openstack dashboard very slow (compare to my old Openstack deployment)
Then i do some check on an instance:
$ time curl http://169.254.169.254/openstack
2012-08-10
2013-04-04
latest
real 0m5.605s
user 0m0.004s
sys 0m0.004s
5 seconds for a simple API query !??
in quantum-ns-metadata-proxyxxxx.log, i saw:
2013-07-25 17:17:09 DEBUG [quantum.agent.metadata.namespace_proxy] Request: GET /openstack HTTP/1.0

I take a look at metadata-agent.log, and saw almost request/response finished @17:17:09
But the last finished @17:17:14
2013-07-25 17:17:14 DEBUG [quantum.agent.metadata.agent] {'date': 'Thu, 25 Jul 2013 10:17:14 GMT', 'status': '200', 'content-length': '28', 'content-type': 'text/html; charset=UTF-8', 'content-location': u'http://172.30.1.14:8775/openstack'}
I enabled slow query log on MySql, but can't find any slow query.
Do you know possible problems in this situation?
Thank you very much!
