Investigate delays before receiving a query #45
Description
Sometimes request handler reports that it took 5-13 seconds to execute the query. However, from the logs it's seen that most of that time was spent somewhere before the query was even received from transport lib.
What's common across these events is the log entry Kademlia event received: UnroutablePeer { peer: PeerId("<portal peer id>") } about the time when the query is supposed to be started
