If that delay is almost exactly 30 seconds, and the client is running
a misconfigured firewall which doesn't reject connection requests, you
are suffering from auth timeouts. Try disabling rfc1413 requests.

If rfc1413 is not the issue, try running a daemon (on a different
port?) with -d and see where the delays occur.

If TLS is in the game, you might have an entropy issue.
