Redis-benchmark测试Redis性能

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、[b]redis-benchmark -t set,lpush -n 100000 -q
[/b]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
