Hello.

I'm developer of Kadu IM that uses libiris as its XMPP backend. Recently we got following bug report: http://www.kadu.im/redmine/issues/2850 (please ignore md5 hashes of libiris in it, there are from our repo https://gitorious.org/kadu/libiris and may be different than yours).

I've check that on Windows and connection to Facebook chat can take up to 60 seconds on my PC. I've installed PSI-IM from http://psi-im.org/download/ and result it the same. Please note that connection is still very fast on Linux on the same PC and network.

I'll try to find that bug but maybe you do know what could cause that?

most probably ipv6 problem. try to use ipv4 address istead of host name.

I'll implement "happy eyeballs" one day and this will be fixed

Kadu has switched to QXmpp recenlty. It solved the problem.
