sshd being slow -- hardware related?

Almost invariably extended SSH login is due to malfunctioning DNS. Make 
sure that your LAN has correct DNS ... if you are stuck then make sure the 
login machine is listed in /etc/hosts ... your machine you are trying to 
SSH to is most likely attempting to do a name lookup and failing. When the 
timeout is reached it lets you in.
