We have a debate goning on here as to if we need to populate the
"Preferred Server" field in the Client. The reason for the debate
stems from the fact that our users are experiencing slow login times
and some folks have learned that placing a servername (a server with a
R/W replica) seems to diminish the login time. We are on a fiber ring
and most of the replicas on our various servers are read only (don't
really know if that makes a difference).

Is the Preferred Server really needed in the Client settings?
