Title:
  Dashboard take 5-10 secs for OpenStack operations

Status in OpenStack Dashboard (Horizon):
  New
Status in horizon package in Ubuntu:
  New

Bug description:
  Dashboard takes around 5-10secs for OpenStack operations (e.g opening instance's page etc) from project panel in admin tenant. Although, if we open any page from admin panel, it takes around 2-3 seconds. Similarly, if we open any page from any other tenant, 5-10 secs are consumed.
  CLI commands seem to be working fine as they take around 1-3.5 secs.

  Please let me know the logs to share. Neutron, Keystone, Nova logs
  doesn't show any errors regarding slowness in API calls.

  OpenStack Release: Mitaka
  Horizon version: 9.1.0
