Redis-benchmark是官方自带的Redis性能测试工具，可以有效的测试Redis服务的性能。
使用说明如下：
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 --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.
测试命令事例：
1、redis-benchmark -h 192.168.1.201 -p 6379 -c 100 -n 100000
100个并发连接，100000个请求，检测host为localhost 端口为6379的redis服务器性能
2、redis-benchmark -h 192.168.1.201 -p 6379 -q -d 100
测试存取大小为100字节的数据包的性能
3、redis-benchmark -t set,lpush -n 100000 -q
只测试某些操作的性能
4、redis-benchmark -n 100000 -q script load “redis.call(‘set’,’foo’,’bar’)”
只测试某些数值存取的性能
