In fact a routing layer designed for non-blocking, evented, realtime app servers like Node and its ilk — a routing layer that assumes every dyno in a pool is as capable of serving a request as any other — is about as bad as it gets for Rails, where almost the opposite is true: the available dynos are perfectly snappy and the others, until they become available, are useless.
