Limewire is not a server it's a p2p app which means it connects you to other computers all over the world. Uploading can depend on how much bandwidth you have allocated as well as how the uploaders download speed is..
This can have many factors such as ISP's, firewalls, if they have dial up, cable, dsl and if they have configured their limewire properly..
There are definitely no bonuses attached to it...
