Title:
Too many lazy-loads in predictable situations
Status in OpenStack Compute (nova):
Expired
Bug description:
During a normal tempest run, way (way) too many object lazy-loads are
being triggered, which causes extra RPC and database traffic. In a
given tempest run, we should be able to pretty much prevent any lazy-
loads in that predictable situation. The only case where we might want
to have some is where we are iterating objects and conditionally
taking action that needs to load extra information.
On a random devstack-tempest job run sampled on 1-Feb-2016, a lot of
lazy loads were seen:
grep 'Lazy-loading' screen-n-cpu.txt.gz -c
624
We should be able to vastly reduce this number without much work.
