Could you check the following with IPv6 installed (on a machine that
suffers from this problem):
Run: nslookup

And inside nslookup execute:
set q=aaaa
www.firebirdsql.org (or otherwise the hostname of you server)

This should return almost immediately; if it doesn't then your DNS
server (listed as Server: ...) is ignoring AAAA record DNS requests,
this will slow down connecting as usually first an attempt is made to
resolve IPv6 (AAAA record) and then IPv4 (A record).
