java测试redis集群性能

一、目的

         测试Redis集群的读写能力

二、环境

         centos6.8

         redis3.2.9

         内存 2G

         单机上的伪集群

三、测试说明

      测试单位为：个/每分钟

      存入的数据为4K

      1.单线程测试 

        写：键为从"key:1000000"开始依次递增，如"key:1000003"

       2.多线程测试

        写：传入的参数为n，表示启动的线程个数，n的范围为2<=n<=8，第一个线程的起始key为“key:2000000”，第二个是“key:3000000”，第n个是“key:”+(n+1)*10000000

四、代码如下

      其中第一个参数为操作类型，值有write、read、delete、count；第二个参数是指定线程个数，不指定是默认为1
