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。

Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests]> [-k <boolean>]

-h <hostname> Server hostname (default 127.0.0.1) 服务地址
-p <port> Server port (default 6379) 服务端口
-s <socket> Server socket (overrides host and port)
-a <password> Password for Redis Auth
-c <clients> Number of parallel connections (default 50) 并行客户端数量默认50
-n <requests> Total number of requests (default 100000) 测试请求次数默认100000
-d <size> Data size of SET/GET value in bytes (default 2) 数据包大小默认2bytes
-dbnum <db> SELECT the specified db number (default 0)
-k <boolean> 1=keep alive 0=reconnect (default 1) 链接存活时间
-r <keyspacelen> Use random keys for SET/GET/INCR, random values for SADD
Using this option the benchmark will expand the string rand_int
inside an argument with a 12 digits number in the specified range
from 0 to keyspacelen-1. The substitution changes every time a command
is executed. Default tests use this to hit random keys in the
specified range.
-P <numreq> Pipeline <numreq> requests. Default 1 (no pipeline).
-q Quiet. Just show query/sec values
--csv Output in CSV format
-l Loop. Run the tests forever
-t <tests> Only run the comma separated list of tests. The test
names are the same as the ones produced as output.
-I Idle mode. Just open N idle connections and wait.
