redis-benchmark

Redis-benchmark是官方自帶的Redis性能測試工具，能夠有效的測試Redis服務的性能。

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.

測試命令事例

一、redis-benchmark -h 192.168.1.201 -p 6379 -c 100 -n 100000 100個併發鏈接，100000個請求，檢測host爲localhost 端口爲6379的redis服務器性能

二、redis-benchmark -h 192.168.1.201 -p 6379 -q -d 100
測試存取大小爲100字節的數據包的性能

三、redis-benchmark -t set,lpush -n 100000 -q 只測試某些操做的性能

四、redis-benchmark -n 100000 -q script load "redis.call('set','foo','bar')" 只測試某些數值存取的性能

./redis-benchmark -h 192.168.31.209 -p 6379 -c 1000 -n 100000 -k 1 script load "redis.call('get', 'community:220926914592768')"
