Bug Description
When the QoS plugin is enabled, get_ports for about 10K ports takes over 10 minutes.
removing _extend_
reduces the time to around 3 minutes only.
This was tested with stable/stein
The "blame" is with the code that retrieves the network object for each port (unless the port was assigned with a qos policy): https:/
This code should be improved.
Another partial fix can be to skip _extend_

Seems like a duplication of bug 1834484
