My guess would be reverse DNS resolution of the client's address plus
forward resolution of that address.  If you have access to the server,
running the server in debug mode (/path/to/sshd -ddd) would likely give you
a better idea.  If it is DNS timing out, setting "UseDNS no" in sshd_config
will likely help.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
