Great work Ann.
About testing on scale it’s not so problematic because of the Cloud For All project.
Here [1] you can request for a multi node cluster which you can use to
perform tests. Exact requirements are specified on that website.

This is some awesome work, Ann. It's very neat to see that all the
races we've struggled with w.r.t. the l3 scheduler has paid off. I
would definitely like to see how these results are effected by
https://review.openstack.org/#/c/305774/ but understandably 49
physical nodes are hard to come by.

Also, we should see how to best handle of the issue Ann found (and is
tracked at https://review.openstack.org/#/c/305774/). Specifically,
reproducing this should be our goal.

Hi guys!

As a developer I use Devstack or multinode OpenStack installation (4-5
nodes) for work, but these are "abstract" environments, where you are not
able to perform some scenarios as your machine is not powerful enough. But
it is really important to understand the issues that real deployments have.

Recently I've performed testing of L3 HA on the scale environment 49 nodes
(3 controllers, 46 computes) Fuel 8.0. On this environment I ran shaker and
rally tests and also performed some manual destructive scenarios. I think
that this is very important to share these results. Ideally, I think that we
should collect statistics for different configurations each release to
compare and check it to make sure that we are heading the right way.

The results of shaker and rally tests [1]. I put detailed report in google
doc [2]. I would appreciate all comments on these results.
