Comment 2 for bug 1324102

OK, here's the same test for stable/icehouse heat, stable/havana for the other openstack services, using the same VM. (Devstack cloned master for the python clients - can we assume that's not an issue for performance? (Devstack might have a bug here?))
The timings are very similar to those for pure stable/icehouse.
