I agree. If the authentication time is too long, users will feel nervous.
I have found some of users evaluate the performance mostly from their
first login remote server. If the time spent in login is too long, they will
believe the performance of whole ssh is too low. Here, the time of first login
is determined mostly by authentication module.
