redis自己提供的redis-benchmark压测工具，是最快捷最方便的，当然啦，这个工具比较简单，用一些简单的操作和场景去压测

1、对redis读写分离架构进行压测，单实例写QPS+单实例读QPS

redis-3.2.8/src

./redis-benchmark -h 192.168.31.20

-c <clients> Number of parallel connections (default 50)
-n <requests> Total number of requests (default 100000)
-d <size> Data size of SET/GET value in bytes (default 2)
