Public bug reported:

Octavia API instantiates a driver for each request e.g.:

def post():
   ...
   driver = driver_factory.get_driver(provider)
   ...

and then driver goes out of scope after the request. ovn-octavia-driver
currently starts an OVSDB connection when it is instantiated. This is a
very expensive operation, as it requests all of the rows from all of the
monitored tables in the OVN DB and then stores them in memory, just to
throw them all away after the request. For even medium-large
deployments, this can mean the minimum time for any Octavia API request
is > 10s.
