Redis基準 - tw511教學網

Redis基準測試是通過同時執行n個命令來檢查Redis的效能的實用程式。

語法

以下是基準測試命令的基本語法。

yiibai@ubuntu:~$ redis-benchmark [option] [option value]

範例

以下範例通過呼叫100000個命令檢查Redis。

yiibai@ubuntu:~$ redis-benchmark -n 100000  
====== PING_INLINE ======
  100000 requests completed in 1.56 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1

97.59% <= 1 milliseconds
99.78% <= 2 milliseconds
99.83% <= 3 milliseconds
99.86% <= 4 milliseconds
99.91% <= 5 milliseconds
99.98% <= 6 milliseconds
99.99% <= 47 milliseconds
100.00% <= 47 milliseconds
64226.07 requests per second

====== PING_BULK ======
  100000 requests completed in 1.57 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1

98.40% <= 1 milliseconds
99.68% <= 2 milliseconds
99.91% <= 3 milliseconds
99.94% <= 4 milliseconds
99.95% <= 45 milliseconds
100.00% <= 45 milliseconds
63694.27 requests per second

====== SET ======
  100000 requests completed in 1.49 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1

97.58% <= 1 milliseconds
99.92% <= 2 milliseconds
99.94% <= 3 milliseconds
100.00% <= 3 milliseconds
67340.07 requests per second

以下是Redis基準測試中可用選項的列表。

序號	選項	說明	預設值
1	`-h`	指定伺服器主機名	127.0.0.1
2	`-p`	指定伺服器埠	6379
3	`-s`	指定伺服器通訊端
4	`-c`	指定並行連線的數量	50
5	`-n`	指定請求的總數	10000
6	`-d`	指定`SET/GET`值的資料大小(以位元組為單位)	2
7	`-k`	1=keep alive, 0=reconnect	1
8	`-r`	使用`SET/GET/INCR`的隨機鍵，SADD的隨機值
9	`-p`	管道`<numreq>`請求	1
10	`-h`	指定伺服器主機名
11	`-q`	強制讓Redis安裝。只顯示`query/sec`值
12	`--csv`	以CSV格式輸出
13	`-l`	生成迴圈，永久執行測試
14	`-t`	只執行逗號分隔的測試列表
15	`-I`	空閒模式。只開啟N個空閒連線並等待

範例

下面的範例顯示了Redis基準實用程式中多個選項的使用。

redis-benchmark -h 127.0.0.1 -p 6379 -t set,lpush -n 100000 -q  

SET: 146198.83 requests per second 
LPUSH: 145560.41 requests per second
