OpenStack Summit April 2013

This session will include the following subject(s):

Scaling/Performance of Keystone:

A number of recent reports have indicated that we have potential scaling and performance issues with Keystone. Examples:
1) Sequential execution when hit by a large batch of requests (200 x create user)
2) Inefficient use of SQL for individual requests (e.g. we don't use PK access for filtering by a PK variable)

The solution is likely multi-fold:
a) Should Keystone use the same multi-process wsgi approach as other projects?
b) Re-evaluation of the backend drivers to enable most efficient use of SQL/LDAP
