Have you tried checking forward and reverse DNS lookups for the machine you are using with the ssh client from the machine you are ssh-ing to? IOW - sshd typically does DNS lookups when you try to connect, that may be taking a while and slowing things down.

i've not checked dns but i didn't think it was the problem
in fact username prompt is fast...but there are 30 sec between this and password prompt...

in any case i check dns now...

thanks

have you noticed anything interesting w.r.t. the pause when you do ssh -vvv? Maybe you could try watching the logfile (via tail) while trying to log in - something interesting may show up.
