Hello Unregistered,
there are at least two bottlenecks:
- your internet connection
- the other sides internet connection
So even if you have a fast connection, the download could be slow. You can advance your download rate if you download from multiple servers, just search for more candidates (this is performed automatically at a certain interval). If you have a slow connection maybe the gnutella network takes too much bandwidth adjust it down on the Phex preferences.
