Title:
Keystone performance degradation in stein comparing with queens
Status in OpenStack Identity (keystone):
Expired
Bug description:
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:
