Comment 3 for bug 862839

Looks like it... for what this calls. This issue is more likely the fact that when doing a "nova list", there's now 2 rpc.calls done per instance. This was a recent change, to try to push all network related stuff through the network service with the notion that this information might be stored in an external service. (An external service will only make this worse.) Things were fine before this. Someone from ozone will likely grab this soon and try to cut this down to a single call per 'nova list'.

Note that EC2 likely has a similar problem now as well.
