NOTE: The default settings work for most people. There is a fundamental tradeoff between anonymity and performance. Tunnels longer than 3 hops (for example 2 hops + 0-2 hops, 3 hops + 0-1 hops, 3 hops + 0-2 hops), or a high quantity + backup quantity, may severely reduce performance or reliability. High CPU and/or high outbound bandwidth usage may result. Change these settings with care, and adjust them if you have problems.
