Redis-benchmark为Redis性能测试工具。

指令说明:

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

-h <hostname>      Server hostname (default 127.0.0.1)
-p <port>          Server port (default 6379)
-s <socket>        Server socket (overrides host and port)
-c <clients>       Number of parallel connections (default 50)
-n <requests>      Total number of requests (default 10000)
-d <size>          Data size of SET/GET value in bytes (default 2)
-k <boolean>       1=keep alive 0=reconnect (default 1)
-r <keyspacelen>   Use random keys for SET/GET/INCR, random values for SADD
  Using this option the benchmark will get/set keys
  in the form mykey_rand:000000012456 instead of constant
  keys, the <keyspacelen> argument determines the max
  number of values for the random number. For instance
  if set to 10 only rand:000000000000 - rand:000000000009
  range will be allowed.
-P <numreq>        Pipeline <numreq> requests. Default 1 (no pipeline).
-q                 Quiet. Just show query/sec values 只显示每秒钟能处理多少请求数结果
--csv              Output in CSV format
-l                 Loop. Run the tests forever 永久测试
-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.

实例:

redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100  
SET/GET 100 bytes 检测host为127.0.0.1 端口为6379的redis服务器性能


redis-benchmark -h 127.0.0.1 -p 6379 -c 5000 -n 100000 
5000个并发连接，100000个请求，检测host为127.0.0.1 端口为6379的redis服务器性能 




benchmark工具测试信息：
测试命令：
redis-benchmark -n 100000 -c 60
向redis服务器发送100000个请求，每个请求附带60个并发客户端
结果（部分）：
====== SET ======
对集合写入测试
  100000 requests completed in 2.38 seconds
100000个请求在2.38秒内完成
  60 parallel clients
每次请求有60个并发客户端
  3 bytes payload
每次写入3个字节的数据
  keep alive: 1
保持一个连接，一台服务器来处理这些请求


93.06% <= 15 milliseconds
99.96% <= 31 milliseconds
99.98% <= 46 milliseconds
99.99% <= 62 milliseconds
100.00% <= 62 milliseconds
所有请求在62毫秒内完成
42105.26 requests per second
每秒处理42105.26次请求
