+ 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.
