Redis-benchmark为Redis性能测试工具。
指令说明:
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 只显示每秒钟能处理多少请求数结果 --csv Output in CSV format -l Loop. Run the tests forever 永久测试 -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.
实例:
redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100
SET/GET 100 bytes 检测host为127.0.0.1 端口为6379的redis服务器性能
redis-benchmark -h 127.0.0.1 -p 6379 -c 5000 -n 100000
5000个并发连接，100000个请求，检测host为127.0.0.1 端口为6379的redis服务器性能
benchmark工具测试信息：
测试命令：
redis-benchmark -n 100000 -c 60
向redis服务器发送100000个请求，每个请求附带60个并发客户端
结果（部分）：
====== SET ======
对集合写入测试
100000 requests completed in 2.38 seconds
100000个请求在2.38秒内完成
60 parallel clients
每次请求有60个并发客户端
3 bytes payload
每次写入3个字节的数据
keep alive: 1
保持一个连接，一台服务器来处理这些请求
