Public bug reported:

I am using neutron-ovs-agent using openvswitch firewall, there are
around 40 ports with same security group on the same compute node. it
seems update security group for each port will consume near 3 seconds
which sums up to around 100 seconds in total. This significantly affects
the speed of spawning virtual machines.
