This bug isn't very useful. Targeted bugs for specific performance
increases would be better. Marking this as "Invalid" please open bugs

Bug description:
  Im currently using Keystone as the auth-server in Swift.
  We have done performance test on our solution and we found that performance of keystone+swift is quite low, only 200 ops/s. While with the same setup the throughput can be improved to 7k ops/s by replacing keystone with swauth
  We found the keystone process is fully saturating one sandy bridge core. This looks like a scalability issue.
  Would be good if keystone could scale up well on a multi-core server.
