This time with 1000 servers:
$ openstack --os-compute-api-version 2.73 server list | grep test-vm | wc -l 1000
Without the patch here are the timings over 10 runs:
http://paste.openstack.org/show/753152/
The average is 5.7822576.
With the patch here are the timings over 10 runs:
http://paste.openstack.org/show/753153/
The average is 5.2145055 which is better but not very noticeable, especially in an unrealistic scenario like I have where I have hundreds of servers on a single compute node.
Based on this I'll drop the severity on this bug to low.
