使用redis-benchmark 对redis进行性能测试

使用例子

针对 192.168.1.1 上的redis 使用20个客户端发起100k请求

redis-benchmark -h 192.168.1.1 -p 6379 -n 100000 -c 20

测试127.0.0.1:6379 1000000 次 SET 命令请求， 使用100000000个不同的key

redis-benchmark -t set -n 1000000 -r 100000000

指定命令同时指定输出格式为CSV

redis-benchmark -t ping,set,get -n 100000 --csv

使用eval调用lua

redis-benchmark -r 10000 -n 10000 eval 'return redis.call("ping")' 0

命令参数

 -h <hostname>      Server hostname (default 127.0.0.1)
 -p <port>          Server port (default 6379)
 -s <socket>        Server socket (overrides host and port)
 -a <password>      Password for Redis Auth
 -c <clients>       Number of parallel connections (default 50)
 -n <requests>      Total number of requests (default 100000)
 -d <size>          Data size of SET/GET value in bytes (default 2)
 -dbnum <db>        SELECT the specified db number (default 0)
 -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 expand the string __rand_int__
  inside an argument with a 12 digits number in the specified range
  from 0 to keyspacelen-1. The substitution changes every time a command
  is executed. Default tests use this to hit random keys in the
  specified range.
 -P <numreq>        Pipeline <numreq> requests. Default 1 (no pipeline).
 -e                 If server replies with errors, show them on stdout.
                    (no more than 1 error per second is displayed)
 -q                 Quiet. Just show query/sec values 只输出简单的请求和耗时
 --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.
