同时执行多个命令的Redis性能测试到底多简单
一、服务器环境二、Redis 之 redis-benchmark
redis 提供了 redis-benchmark 工具便于我们做性能测试，可以使用 redis-benchmark- h 查看参数。
三、Docker Redis测试
单并发测试
测试命令
./redis-benchmark -c 1 -n 20000 -d 30720 -t set,get测试结果每秒是 8000+的QPS
多并发测试
假设 10并发，20000个请求，每次请求数据包大小为 30KB，只进行set和get测试。
./redis-benchmark -c 10 -n 20000 -d 30720 -t set,get====== SET ======

接下来测试 -P 命令
20000个请求，每次请求数据包大小为 30KB，只进行set和get测试。
