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

Without scientific data at this point, I can confirm that every CLI/API
call I make on a freshly-deployed Xenial-Mitaka arm64 cloud is
noticeably sluggish compared with x86 deploys, where the x86 machines
are 6 years old, have 75% of the RAM, and less than half the advertised
cores.

This is worth profiling without OpenStack in the mix.

I'd like to have HWCERT or Server Team or Kernel Team to provide system
performance profiling methodology info (presuming there is an existing
approach). Then I'd like to exercise that on these arm64 machines and
the x86 machines, then compare to get baseline info (again, absent
OpenStack).

@raghu: please see if you can gather info from other teams and direct
that info here. TIA!

Title:
  ARM Opentack  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.
