摘要：指令说明只显示每秒钟能处理多少请求数结果永久测试示例检测为端口为的服务器性能个并发连接，个请求，检测为端口为的服务器性能测试信息向服务器发送个请求，每个请求附带个并发客户
指令说明
Usage: redis-benchmark [-h ] [-p ] [-c ] [-n [-k ]
-h Server hostname (default 127.0.0.1)
-p Server port (default 6379)
-s Server socket (overrides host and port)
-c Number of parallel connections (default 50)
-n Total number of requests (default 10000)
-d Data size of SET/GET value in bytes (default 2)
-k 1=keep alive 0=reconnect (default 1)
-r 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 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 Pipeline 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 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.
示例
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
测试信息
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
93.06% <= 15 milliseconds
99.96% <= 31 milliseconds
99.98% <= 46 milliseconds
99.99% <= 62 milliseconds
100.00% <= 62 milliseconds # 所有请求在62毫秒内完成
42105.26 requests per second #每秒处理42105.26次请求
其它测试
