前言:
Redis-benchmark:
Redis 自带了一个叫 redis-benchmark 的工具来模拟 N 个客户端同时发出 M 个请求。 (类似于 Apache ab 程序)。你可以使用 redis-benchmark -h 来查看基准参数。
参数简介:
支持以下参数:
用法:redis-benchmark [-h <主机>] [-p <端口>] [-c <客户端>] [-n <请求]> [-k <布尔>]
-h <主机名>服务器主机名(默认值为127.0.0.1)
-p <端口>服务器端口(默认6379) # 作者喜欢的一个女明星名字9键就是6397 !!!∑("htmlcode">
redis-benchmark -h localhost -p 6379 -a adc.123 -c 100 -n 100000 -q redis-benchmark 后面跟参数 这里我测试了 -c100并发和-n 100000请求 -q 静默,不显示细节
以下是测试结果
[root@localhost bin]# redis-benchmark -h localhost -p 6379 -a adc.123 -c 100 -n 100000 -q

可以看到 set 写入 每秒约 12w,读取每秒约12w,综合每秒约12w。
下面我们把 -q去掉,看下详细信息,应为太多,只调取了写入和读取的信息。
