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

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

Thanks in advance.
