despite compression etc, running as an ultrapeer still reduces upload bandwidth a lot. for hosts with popular content, it seems to make sense to disable ultrapeer, especially considering the percentage of hosts running as ultrapeers nowadays. who's gonna serve files if everyone is busy being a hub?

as ultrapeer
49 hosts, all incoming
longest connection 41 minutes in 1 hour uptime
at the beginning, lots of non limewire hosts, but they all eroded away within 5 minutes
8.5 k gnutella upstream
5.2 k http upstream
7.0 k gnutella downstream
0.3 k http downstream


as leaf
4 ultrapeers
all limewire
many of them short-lived (less than 10 min)
0.1 k gnutella upstream
13.3 k http upstream
.4 k gnutella downstream
.3 k http downstream
