Hi,

yes - I've used 'UseDNS Yes' and UseDNS No' and restarted sshd each time 
and that didnt change anything.  also there are other clients that log 
into the FreeBSD (sshd side) box fine without slowing down.  that is why 
I am wondering if it something more on the client end.  But then to 
repeat the OSX client side logs into other sshd servers without lag.

it is something specific to my OSX (ssh client)  machine and the FreeBSD 
box (sshd side)

any other clues?

Cheers,

Noah
