Engaging ultrapeer caused massive, heavy, relentless traffic when monitored; then connection went down. I'm on DSL. It also slowed MY searches. Believe me, I've twiddled with all the controls/parameter/settings possible, and it's just better to have Ultrapeer disabled WHILE YOU ARE LOOKING YOURSELF. Often, however, I will engage ultrapeer for other people's benefit, for as long as it holds and connection stays. I have not lost connection with Ultrapper disabled.
