A peer can be one of 2 things, depending what mode your client is in.

- If in leaf mode, you're connecting to Ultrapeers that are shielding you from a lot of the common gnutella traffic, Ultrapeers are meant to handle the data more effeciently, since it's usually a client with a good uptime average and connection speed - preventing bottlenecks.
In this mode the Ultrapeers you're connected to show as 'peers' and you should have 0 leafs, since you yourself are one.


IF in Ultrapeer mode, your peers are other Ultrapeers and leafs are the clients connected to you.


What determines what mode you're in? You can alter these settings in options > preferences > network > advanced button.

By default, only clients with a good connection speed and high uptimes, are made eligible to become an Ultrapeer. You can however also force this option.

hope that helps
