Optimization on _modify_rules in patch https://review.openstack.org/#/c/77549/ did shorten time , but still the time is not short enough.
I found the time to finish the _apply_synchronized takes more than half of hour(36 minutes in my environment) when the number of active vms in cloud is 982.
This will lead the time to bring port up when booting an instance will last very long. Optimazation on _modify_rules need be done to fit the situation of Large-scale deployment.
