Why is Lime Wire So Popular?

• Java support
• Ultrapeers
• Firewall-to-firewall transfers

What is Java in Lime Wire?

Lime Wire and Java may run slowly on very old computers with small amounts of memory (RAM). In addition, starting up and making the initial nework connections in a Lime Wire client generally takes longer than with other P2P clients. These performance limitations are inherent in the Java environment but considered a relatively minor issue to Lime Wire users.

To achieve the best Gnutella network connections, Lime Wire clients should be left connected and running for an extended time period.

What are Ultrapeers in Lime Wire?

Ultrapeers allow Gnutella to support a greater number of users, by shifting the network load toward clients better able to accommodate it. When Lime Wire users search for files and initiate downloads, the Gnutella network protocol logic ensures those clients are more likely to connect to ultrapeers than to ordinary peers.

For example, Lime Wire users with a new high-end PC running Windows XP and a high-speed cable modem Internet connection are good candidates to become ultrapeers, while users with old PCs running Windows 98 over dial up connections would not become ultrapeers. Lime Wire automatically designates ultrapeers, although individual users can opt-out of this mode through the client.

What Are Firewall-to-Firewall Transfers in Lime Wire?

If two peers want to share a file, and one is blocked by a firewall, some P2P network protocols detect this situation and can work around it by moving the responsibility of making connections to the peer not firewalled. However, if both peers sit behind firewalls, connections become much more complex to complete. Lime Wire was the first client to provide solutions for this scenario.

Lime Wire works with some but not all types of firewalls.
