Public bug reported: Problem like that was mentioned in Vancouvers's "Challenges & lessons from operating OpenStack at Scale" forum session (https://etherpad.opendev.org/p/challenges-largescale) In some cases, neutron metadata agent may put a lot of load on the RPC bus and neutron server as every time VM is asking for some of the metadata, this agent needs to find out what the id of the instance is. Because of that it sends RPC message to get port details every time. It could be potentially avoided by some simple caching of the instance id in the agent's side.
