Hello, For exit router selection path-spec says that;
"For circuits that do not need to be "fast", when choosing among multiple candidates for a path element, we choose randomly. For "fast" circuits, we pick a given router as an exit with probability proportional to its bandwidth." Could anybody explain why Tor pick exit router with probability proportional to its bandwidth *only for fast circuits*? As far as i know Tor uses this technique for load-balance. But why it uses this technique only for fast circuits? Thanks in advance.
