Hey folks,
Just wanted to check back in on the resource consumption topic.
Looking at my measurements the TripleO group has made quite a bit of
progress keeping our enqued zuul time lower than our historical average.
Do you think we can measure where things stand now and have some new
numbers available at the PTG?

/me notes we had a blip on 3/25 but there was a one off issue w/ nodepool
in our gate.

Marios Andreou has put a lot of time into this, and others as well.  Kudo's
Thanks all!
