I'm not convinced.. jabber.org has 178000+ registered users (we purge inactive accounts, so this is a pretty decent number). The largest roster has 1519 items. Only 100 users have 200+ items in their roster (this is 0.05%). The average number of roster items is currently 5.8. The standard deviation of # of roster items is 18.5. So the VAST majority of our users have VERY small rosters. Also note that folks with very large rosters are a lot more likely to have a smaller percentage of users online. So the total # of presence packets is going to be smaller. Also please checkout http://status.jabber.org. You can see that normal operations consume very little bandwidth (for a server) and we're serving 10000+ users during our peak operations. Honestly, I think we're worrying about a non-issue. As someone else brought up, a server could also use JEP-131 to allow remote servers to do the de-multiplexing of presence packets. pgm. _______________________________________________ jdev mailing list [EMAIL PROTECTED] http://mail.jabber.org/mailman/listinfo/jdev
