Hmm, looking at:
https://github.com/openstack/keystonemiddleware/compare/4.0.0...4.1.0 the
only change that I can think of that might be the culprit is:
https://github.com/openstack/keystonemiddleware/commit/f27d7f776e8556d976f75d07c99373455106de52
I'll dig into this some more soon, but it might be worth trying things out
with that commit reverted.

Hi all,
We noticed a major jump in the neutron tempest and API test run times
recently in Neutron. After digging through logstash I found out that it
first occurred on the requirements bump here:
https://review.openstack.org/#/c/265697/
After locally testing each requirements change individually, I found that
the keystonemiddleware change seems to be the culprit. It almost doubles
the time it takes to fulfill simple port-list requests in Neutron.
Armando pushed up a patch here to confirm:
https://review.openstack.org/#/c/270024/
Once that's verified, we should probably put a cap on the middleware
because it's causing the tests to run up close to their time limits.
Kevin,
As usual your analytical skills are to be praised.
I wonder if anyone else is aware of the issue/s, because during the usual
hunting I could see other projects being affected and showing abnormally
high run times of the dsvm jobs.
I am not sure that [1] is the right approach, but it should give us some
data points if executed successfully.
Cheers,
Armando
