Redis 压力测试--redis-benchmark
redis-benchmark使用参数介绍
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。
redis 性能测试工具可选参数如下所示:
压测示例
压测需要一段时间,因为它需要依次压测多个命令的结果,如:get、set、incr、lpush等等,所以我们需要耐心等待,如果只需要压测某个命令,如:set,那么可以在以上的命令后加一个参数-t:
redis-benchmark -h 127.0.0.1 -p 6379 -n 100000 -c 50 -t set
====== SET ====== 100000 requests completed in 0.40 seconds ## 0.4秒处理了100000个请求 50 parallel clients ## 50个并发 3 bytes payload ## 每次存取3 byte keep alive: 1 host configuration "save": 3600 1 300 100 60 10000 host configuration "appendonly": no multi-thread: no 22.96% <= 0.1 milliseconds 99.96% <= 0.2 milliseconds 100.00% <= 0.2 milliseconds 253164.55 requests per second
这样看起来数据很多,如果我们只想看最终的结果,可以带上参数-q,完整的命令如下:
示例2:
redis-benchmark -h 127.0.0.1 -p 6379 -n 100000 -c 50 -q
