When pressure is low, every backend's score will be same, in 2.3 the function find_best_backend will always chose candidates.end(), although it is not a problem, but it make people confuse, we receive a lot of complains，so we think it is better to let every backend execute same number of queries in such situation . |

The least recently used server is now used by readwritesplit for equally good servers. |
