I also see this impact. With the situation we have *today* I agree with
Dave that we don't save much traffic and stanzas with repeaters. There
is nearly no PubSub usage at all today, and in the most Muc rooms we
have only 5-30 participants. If I look at the participants of jdev today
than the most users have local jabber.org Jids, and max. 2 or 3
participants are on the same federated server. People join and leave, so
there will be a tie between the stanzas we save in the repeater and the
overhead to maintain the distribution list in the repeater.
But we have to look forward. We all want to see the killer pubsub
application with 100K subscribers and more. We also want people to
switch from IRC to Muc and see tons of Muc rooms with 100+ participants.
And maybe we define other 1->n protocols in the future. In the long run
we will benefit a lot from repeaters.
Compression is great and saves lots of bandwidth. Compression +
Repeaters is even better and will save more bandwidth and stanzas.
