redis压力测试工具---redis-benchmark

redis做压测可以用自带的redis-benchmark工具，使用简单

(venv_py36) [[email protected] ~]# which redis-benchmark

/usr/bin/redis-benchmark

压测命令：redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000

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：get，那么可以在以上的命令后加一个参数-t（红色部分）：

1、redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -t get

(venv_py36) [[email protected] ~]# redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -t get

====== GET ======

  10000 requests completed in 0.12 seconds

  50 parallel clients

  3 bytes payload

  keep alive: 1

 

96.17% <= 1 milliseconds

97.35% <= 2 milliseconds

98.97% <= 3 milliseconds

99.01% <= 6 milliseconds

99.17% <= 7 milliseconds

99.58% <= 8 milliseconds

99.70% <= 9 milliseconds

100.00% <= 9 milliseconds

80645.16 requests per second

2、redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -t set

(venv_py36) [[email protected] ~]# redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -t set

====== SET ======

  10000 requests completed in 0.12 seconds

  50 parallel clients

  3 bytes payload

  keep alive: 1

 

96.55% <= 1 milliseconds

98.01% <= 2 milliseconds

98.04% <= 3 milliseconds

98.99% <= 4 milliseconds

99.63% <= 5 milliseconds

99.92% <= 6 milliseconds

100.00% <= 6 milliseconds

81967.21 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：

3、redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -q

(venv_py36) [[email protected] ~]# redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -q
