Without scientific data at this point, I can confirm that every CLI/API

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

ARM Opentack API/Dashboard calls are very slow
Status in horizon package in Ubuntu:
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.
