使用Redis-benchmark为Redis性能测试
Redis-benchmark为Redis性能测试工具。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> -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, theargument 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 Pipelinerequests. 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 > 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
