Sorry for the confusion.
As I said I get quick response for the password and then that line 
showing the "Last Login: ..." stuff.
At this point I suppose that connection to the sshd has been established.
So I go with your suspicion about the profile or login files of the shell.
The thing that puzzles me ist that I do it from localhost to localhost 
and opening a cygwin terminal with bash on localhost takes less than 2 
seconds.
 From my understanding the login/profile stuff should be almost the same.
One thing that comes to my mind is that there may be something with my 
domain credentials.
The password I need to supply is my windows domain login password, so I 
think I am logged in as the domain user.
But if there is something wrong with the credentials it could be that 
during the login process there are attempts to access network shares 
which possibly fail and give timeouts.
Thanks for pointing me in that direction so I am going to put some set 
-x into the login scripts to see if I can find the reason.

cygwin ssh login long login delay while showing "last login"

[Peter]

I have installed the cygwin ssh daemon on my w7 box with cygwin64.

When I try to login I always get a long delay or timeouts on the client 
side.

I get quick response for the password and then a showing "Last login: ..."

At this point the connection hangs for about 30s to 1min before I 
finally get a login .

This is what it shows when I try to do an ssh to my local host from my 
local host:

$ ssh testuser@myw7host
testuser@myw7host's password:
Last login: Thu Aug  6 12:46:23 2015 from 128.139.80.101

The password request and the Last login is almost instant but then it 
hangs for about a minute before I get the login .

I also tried to ssh testuser@localhost or testuser@128.139.80.101  but 
the effect is the same.

How can I troubleshoot the issue?

Peter

It's unclear to me whether you're saying the delay is in completing the
"last login" line (and showing the IP address) or the delay is after the IP
address is shown and before you get a shell prompt.  If it's the first of
these, it sounds like there's a DNS timeout trying to find the machine name
for that address and failing.  If it's the second of these, I would suspect
something in one of the profile or login files for the shell involved.
