Redis 性能测试

        Redis 性能测试是通过同时执行多个命令实现的。

        Redis 性能测试的基本命令如下：

redis-benchmark [option] [option value]

        以下实例同时执行 1000 个请求来检测性能：

redis-benchmark -h 172.19.24.222 -p 6381 -c 100 -n 1000
====== PING_INLINE ======
  1000 requests completed in 0.04 seconds
  100 parallel clients
  3 bytes payload
  keep alive: 1

0.10% <= 1 milliseconds
48.30% <= 2 milliseconds
98.80% <= 3 milliseconds
100.00% <= 3 milliseconds
26315.79 requests per second

====== PING_BULK ======
  1000 requests completed in 0.04 seconds
  100 parallel clients
  3 bytes payload
  keep alive: 1

0.10% <= 1 milliseconds
59.40% <= 2 milliseconds
99.50% <= 3 milliseconds
100.00% <= 3 milliseconds
27027.03 requests per second

====== SET ======
  1000 requests completed in 0.04 seconds
  100 parallel clients
  3 bytes payload
  keep alive: 1

0.10% <= 1 milliseconds
54.70% <= 2 milliseconds
93.80% <= 3 milliseconds
99.80% <= 4 milliseconds
100.00% <= 4 milliseconds
27777.78 requests per second

====== GET ======
  1000 requests completed in 0.03 seconds
  100 parallel clients
  3 bytes payload
  keep alive: 1

0.10% <= 1 milliseconds
76.40% <= 2 milliseconds
100.00% <= 2 milliseconds
33333.34 requests per second

....省略

====== MSET (10 keys) ======
  1000 requests completed in 0.04 seconds
  100 parallel clients
  3 bytes payload
  keep alive: 1

0.10% <= 1 milliseconds
27.70% <= 2 milliseconds
96.80% <= 3 milliseconds
100.00% <= 3 milliseconds
25000.00 requests per second

        Redis 性能测试工具可选参数如下：

序号	选项	描述	默认值
1	-h	指定服务器主机名	127.0.0.1
2	-p	指定服务器端口	6379
3	-s	指定服务器 socket
4	-c	指定并发连接数	50
5	-n	指定请求数	10000
6	-d	以字节的形式指定 SET/GET 值的数据大小	2
7	-k	1=keep alive 0=reconnect	1
8	-r	SET/GET/INCR 使用随机 key, SADD 使用随机值
9	-P	通过管道传输 <numreq> 请求	1
10	-q	强制退出 redis。仅显示 query/sec 值
11	--csv	以 CSV 格式输出
12	-l	生成循环，永久执行测试
13	-t	仅运行以逗号分隔的测试命令列表。
14	-I	Idle 模式。仅打开 N 个 idle 连接并等待。
