File Sharing Ultrapeer?
 

I have been using Limewire(curently 4.4.5) for a couple of months now, and a sometimes read posts here. My home computer (AMD Athalon XP 2600, 512 RAM, and cable connection) almost always acts as an ultrapeer. I am sharing about 3500 files, is that too many files? Some posts make it sound like that is too much for ultrapeer mode. Is it possible to share too many files? I have my uploads set at 10, should I lower that when I'm an ultrapeer? Should any of my settings be different?

Thanks

Jon
