Hello!

If you have lots of files that you are sharing then you could try to limit the upload bandwidth used and also the amount of available upload slots(number of persons that are able to download from you at the same time). That way people might be getting slower download speeds from you but the traffic load on you would also decrease enabling you to handle the traffic for distributing Gnutella messages/packets as an UltraPeer.

If you preferr to share lots of files and enabeling more persons to download from you at maximum speed then you should remain as a Leaf Node.
