That kind of performance testing is something we need more of.  It's
likely going to depend on several factors, including the number of
resources you have in OVN_Northbound and the number of hypervisors
running ovn-controller.

This is obviously something we want to test extensively and optimize as
we discover where the bottlenecks are.  Once you start using it, sharing
your experience would be very useful.
