Open Stack

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
