Do you see the same delay when identifying the server by IP address
(rather than by name)?

If this is the problem discussed before (waiting for the IPv6 connection
attempt to time out), it should be possible to change the preference via
gai.conf (RFC 3484).
We might also consider extending the new connection string format
inet://... to variants inet4://... and inet6://... which would enforce
AF_INET or AF_INET6.
