Is the FreeBSD box overloaded? And does your client show up in forward
and reverse DNS for the FreeBSD box? The almost mandatory DNS and
reverse DNS lookups for connecting clients can cause significant delays.

I agree. Have found the FreeBSD sshd insists on doing reverse DNS lookups no matter what I have tried in /etc/ssh/sshd_config. Using Google suggests this situation is not unusual for others with Linux.

A properly functioning local caching named cut inside ssh connection time down from 30 seconds to 5 seconds. FreeBSD 5.5-Stable on PII-450, Mac OS X, 192.168.0.0/24, both on the same 10/100 network switch.
