You could try tuning a few settings in the manual:

       msgminwait sec

       Defines  the  time screen delays a new message when one message
is currently dis‐
       played.  The default is 1 second.

       msgwait sec

       Defines the time a message is displayed if screen is not
disturbed by  other  ac‐
       tivity. The default is 5 seconds.
