PLAIN is the default. It is ALWAYS available, even if you have other
methods in place. Therefore, your system now just drops down to PLAIN
before trying anything else ! Therefore, you will see a speed increase
as the system just logs in , rather than trying anything else first.
Of course, if the other AUTH methods you advertise work, then they
should be similar in speed.
What generally happens is that the server will advertise an AUTH 
that it doesn't support. Then you see speed loss due to try and catch
handshaking while the client drops down each time to a lower level of
authentication. This can kill sessions. So its try, stop and wait, try
something else, stop and wait, try stop and wait, oh that one works !!
