[Bug 1664764] Re: ARM OpenStack API/Dashboard calls are very slow

[dann frazier]

Last week, sfeole deployed a new arm64-only OpenStack setup in our lab
(xenial/newton). This is a hybrid setup with a mixture of X-Gene and
ThunderX hardware. I am not able to reproduce on this setup:

$ time glance image-list
+--------------------------------------+-------------+
| ID                                   | Name        |

+--------------------------------------+-------------+

real	0m3.437s
user	0m1.988s
sys	0m0.132s


So, either this issue was fixed in an update somewhere, or something
about this hybrid setup is avoiding it. Note that I originally saw this
on a ThunderX-only deployment. One notable difference between these
systems is core count - X-Gene is 8 core, ThunderX (1-socket) is 48.
Perhaps something is scaling poorly?

Title:
  ARM OpenStack API/Dashboard calls are very slow

Status in horizon package in Ubuntu:
  New

Bug description:
  dann frazier (dannf) on 2016-12-23 :

  I'm using openstack-base deployed on an arm64-only MAAS
  (xenial/newton). Both the CLI and dashboard are very slow to respond.
  CLI commands (e.g. nova list) take about 15s to complete. Logging into
  the dashboard takes more than 30s. 'top' shows plenty of available
  CPU/memory on the dashboard node.

  Note: This isn't new - it is something we've observed with previous
  versions of Ubuntu OpenStack as well, but haven't yet gotten to the
  bottom of it.
