redis-benchmark 测试redis性能

用法：redis-benchmark [-h ] [-p ] [-c ] [-n [-k ]

-h      Server hostname (default 127.0.0.1)
-p          Server port (default 6379)
-s        Server socket (overrides host and port)
-c       Number of parallel connections (default 50) 并发客户端数
-n      Total number of requests (default 10000)  请求数量
-d          Data size of SET/GET value in bytes (default 2) set 数据大小
-k       1=keep alive 0=reconnect (default 1) 是否采用keep alive模式
-r   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 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        Pipeline requests. Default 1 (no pipeline). 是否采用Pipeline模式请求，默认不采用
-q                 Quiet. Just show query/sec values 仅仅显示查询时间
--csv              Output in CSV format  导出为CSV格式
-l                 Loop. Run the tests forever 循环测试
-t         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.
