redis-benchmark為redis效能測試工具。
指令說明:
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 只顯示每秒鐘能處理多少請求數結果
--csv output in csv format
-l loop. run the tests forever 永久測試
-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.
例項:redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100
set/get 100 bytes 檢測host為127.0.0.1 埠為6379的redis伺服器效能
redis-benchmark -h 127.0.0.1 -p 6379 -c 5000 -n 100000
5000個併發連線，100000個請求，檢測host為127.0.0.1 埠為6379的redis伺服器效能
benchmark工具測試資訊：
測試命令：
redis-benchmark -n 100000 -c 60
向redis伺服器傳送100000個請求，每個請求附帶60個併發客戶端
結果（部分）：
*****= set *****=
對集合寫入測試
100000 requests completed in 2.38 seconds
100000個請求在2.38秒內完成
60 parallel clients
每次請求有60個併發客戶端
3 bytes payload
每次寫入3個位元組的資料
keep alive: 1
保持乙個連線，一台伺服器來處理這些請求
93.06% <= 15 milliseconds
99.96% <= 31 milliseconds
99.98% <= 46 milliseconds
99.99% <= 62 milliseconds
100.00% <= 62 milliseconds
所有請求在62毫秒內完成
42105.26 requests per second
每秒處理42105.26次請求
