You will need to provide more details than "old" vs. "new" OpenStack.
For example...
1) What is your network model in the old vs. new
2) What version of OpenStack is the old
3) Is Keystone used in old and new? If so, what drivers are used in
Keystone?
4) Do you have errors in any of your log files (usually an indication
that something like a timeout or failure on RPC which may affect
performance)
5) Are you using nova-conductor in the new?
6) What database backend are you using?
7) Do a time keystone user-list on both old and new
8) Pastebin your conf files, with passwords removed
The more information you give, the better folks can help you.
Best,
-jay

Compare with my old OpenStack deployment on weaker servers, it took 1/3
in times.

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 0m*5.605s*
user 0m0.004s
sys 0m0.004s
5 seconds for a simple API query !??
in quantum-ns-metadata-proxyxxxx.log, i saw:

I take a look at metadata-agent.log, and saw almost request/response
finished @*17:17:09

But the last finished *@**17:17:14

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!
