Hi *,
we're running Openstack on top of Leap 42.1. Since switching to Mitaka,
we're experiencing severe delays when accessing the dashboard - i.e.
switching between "Compute - Overview" and "Compute - Instances" takes
15+ seconds, even after multiple invocations.
I've had a look at the requests, the Apache logs and our control node's
stats and noticed that it's a single call that's taking all the time...
I see no indications of any error, it seems that once WSGI is invoked,
that call simply takes its time. Intermediate curl requests are logged,
so I see it's doing its work. Looking at "vmstat" I can see that it's
user space taking all the load (Apache / mod_wsgi drives its CPU to
100%, while other CPUs are idle - and no i/o wait, no system space etc.).
Current test, switching to "Overview" took 13.09 secs loading
http://control1/project/. Switching back to "Instances" took 14.7 secs
for http://control1/project/instances/. Ain't no fun using the dashboard
that way... and we did not see this with previous releases.
Do others see the same slowness or is it likely some (system or
Openstack) configuration issue on our side?
I believe, I saw something comparable, but thought it was due to my setup.
You mentioned, you already identified a single call taking all the time:
which one is it? Could you please file a bug?

It could be either Horizon or nova API (or both) being slow.
