A larger join/prune message size will result in loss of a larger amount of information when a message is 

lost; with a reduced join/message size, the loss of a single message will bring relatively minor impact.  

By controlling the maximum number of (S, G) entries in a join/prune message, you can effectively 

reduce the number of (S, G) entries sent per unit of time.
