The forum search will e.g. give you this thread: "Improving Gnutella performance"

A very short summary about super peers and other ideas arround (if you're interested):

1. A superpeer concept for dynamic traffic routing = reducing backbone traffic + improves network toplogy + increases horizon (more available files)
2. Search-caches for reducing double/multiple routed traffic = reducing high amout of search backbone traffic
3. Swarming technology = make use of the high amout of wasted bandwith + will spread often requested files + balance load + less "busy" servants (more available files)
4. Add more ideas here.... brainstorming is allways fine
