redis压力测试工具-----redis-benchmark

redis做压测可以用自带的redis-benchmark工具，使用简单

压测命令：redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000

压测需要一段时间，因为它需要依次压测多个命令的结果，如：get、set、incr、lpush等等，所以我们需要耐心等待，如果只需要压测某个命令，如：get，那么可以在以上的命令后加一个参数-t（红色部分）：

1、redis-benchmark -h 127.0.0.1 -p 6086 -c 50 -n 10000 -t get

C:\Program Files\Redis>redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -t get

====== GET ======
10000 requests completed in 0.16 seconds
50 parallel clients
3 bytes payload
keep alive: 1

99.53% <= 1 milliseconds
100.00% <= 1 milliseconds
62893.08 requests per second

2、redis-benchmark -h 127.0.0.1 -p 6086 -c 50 -n 10000 -t set

C:\Program Files\Redis>redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -t set

====== SET ======
10000 requests completed in 0.18 seconds
50 parallel clients
3 bytes payload
keep alive: 1

87.76% <= 1 milliseconds
99.47% <= 2 milliseconds
99.51% <= 7 milliseconds
99.74% <= 8 milliseconds
100.00% <= 8 milliseconds
56179.77 requests per second

这样看起来数据很多，如果我们只想看最终的结果，可以带上参数-q，完整的命令如下：

3、redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -q

C:\Program Files\Redis>redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000 -q
