Title:
  remove_router_interface doesn't scale well with dvr routers

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  With dvr enabled , neutron remove-router-interface significantly
  degrades in response time as the number of l3_agents and the number of
  routers increases.   A significant contributor to the poor performance
  is due to check_ports_exist_on_l3agent.  The call to
  get_subnet_ids_on_router returns an empty list since the port has
  already been deleted by this point.  The empty subnet list is then
  used as a filter to the subsequent call core_plugin.get_ports which
  unexpectedly returns all ports instead of an empty list of ports.
  Erroneously looping through the entire list of ports is the biggest
  contributor to the poor scalability.
