And anyway I don't think the connection rate of ipoib CM is particularly important. And we can always optimize ib_find_pkey as part of the longer-term plan to get rid of ib_find_cached_pkey.
rate of connections per second might be an intresting feature in the context of doing TCP offload eg with SDP, when you want to see how many connetions can a web server or database establish with clients in unit of time. With the cache elimination every new connection will consume two more IB commands (port query and pkey table read).

Let it be. It makes sense to me to eliminate the cache. Or.
