Public bug reported:
I install two ubuntu vms using the same resources (cpu/memory/disks) to
setup devstack. One devstack is using stein branch and the other
devstack is using queens branch.
I have run the same keystone test cases in the two devstack environments
using rally benchmark tool. And the result is keystone performance is
worse in stein comparing with queens (comparing average time for each
keystone api shown below in rally task report).
For Queens devstack env:
