During a lot of port deletions, the OVS agent will build up a lot of remote security group member updates for a single device. Once the call to delete all of the removed remote IP conntrack state gets issued, there will be many duplicated entries for the same device in the devices_with_updated_sg_members dicionary of lists. This results in many duplicated calls to remove conntrack entries that are just a waste of time. The longer it takes to remove conntrack entries, the more of these duplicates build up for other pending changes, to the point where there can be hundreds of duplicate calls for a single device. This just adjusts the conntrack manager clearing logic to make sure it de-duplicates all of its delete commands before it issues them. In a local test on a single host I have 11 threads create 11 ports each, plug them into OVS, and then delete them. Here are the number of conntrack delete calls issued: Before this patch - ~232000 With this patch - ~5200 While the remaining number still seems high, the agent is now fast enough to keep up with all of the deletes.
