   In my opinion, when you use leadactiveloadbalance, the only parameter that determines load balancing is `active`, so worse node will first reach the active limit. When the same volume of water is added, just like two buckets with different volumes,the small bucket will overflow. As for shortestResponseLoadBalance,the load balancing strategy is calculating `average response time `* `active`,the better node'rt is much less than an other.
   In fact,shortestResponseLoadBalance is still not good enough. it never reset statistical time  #8441 and it depends average.Maybe you can have a look at [peakEwmaLoadBalance](https://github.com/apache/dubbo-spi-extensions/pull/68)
