I think that the SSH server regenerates the RSA key every time someone
logs in. Depending on server's CPU, it may take about 30 seconds.
This can be fixed with proper configuration tuning.
Anyway, you showed us a client-side log, whereas the problem is on server.

I think you should stop SSHD (NT service "CYGWIN sshd" or something like
that), and start /usr/sbin/sshd with debug parameters, and watch the
server output. Pay attention, because SSHD in debug mode terminates
after every session, and you'll have to start it again for every test.
