redis之性能介紹(爲什麼那麼快)

1.官方測試工具

1.1.官網地址

https://redis.io/topics/benchmarks

1.2.redis-benchmark介紹

1.redis-benchmark是我們在安裝redis的時候，自帶的一個命令工具

localhost:~ gaoxinfu$ ls -la /usr/local/bin/ |grep redis
-rwxr-xr-x   1 gaoxinfu  admin    113008  3 17 21:01 redis-benchmark
-rwxr-xr-x   1 gaoxinfu  admin   1353456  3 17 21:01 redis-check-aof
-rwxr-xr-x   1 gaoxinfu  admin   1353456  3 17 21:01 redis-check-rdb
-rwxr-xr-x   1 gaoxinfu  admin    268668  3 17 21:01 redis-cli
lrwxr-xr-x   1 gaoxinfu  admin        12  3 17 21:01 redis-sentinel -> redis-server
-rwxr-xr-x   1 gaoxinfu  admin   1353456  3 17 21:01 redis-server
localhost:~ gaoxinfu$ 

1.2.1.redis-benchmark -q -n 100000

1.-q 標示只是展示查詢值
2.-n 請求數數量，相當於模擬多少次請求

我們可以用上面的工具redis-benchmark去測試本地redis服務器的性能
