My application have functionality to send message to group of users and receive message through xmpp. Nothing else. Currently I am using MUC to broadcasting message. To receive message in room, every participant need to join that room. Instead of that can I use group in openfire and broadcast message to group instead of room. In this case, recipient does not need to join room.
Is there any performance impact, if I use group instead of MUC room?
Can I create large volume of group in openfire serve?
