Well, it depends on what you consider by wrongly configured.
Limewire's default configuration is set possibly for 56k modem users as you can't expect from everyone to pay for the more costly broadband connections.
Wether I'm right or wrong, if you kept your default configurations/preferences/options/whatever you wanna call it and you are on a broadband connection, then you're most probably not taking full advantage of your bandwidth.
Go to the Limewire: Open discussion forum and check the sticky about optimal performance (if you haven't already).
