Salut Allinova, normally an UP consumes 5KB/s both down and up. This should not slow down your connection for downloads. However, if your computer is low in ram or cpu, it can slow your computer. If your computer has more than 500MHZ, 256MB ram and a connection better than 256/128kbps, you should not worry. Test it, and if you think it slows you, desactivate the check case in options -> Speed
Right now, gnutella is not lacking UPs, so you can help the network by sharing if you prefer!
Ciao
