Windows 磁盤部分性能數據獲取

Windows 磁盤部分性能數據獲取

摘要

每次晚上加班總有收穫
這次發現了一個fio for windows版本的壓測程序, 準備學習和使用一下. 
https://github.com/axboe/fio/releases

安裝

exe 的正常安裝不用都說直接使用就可以了. 

注意我這變使用的是 x64版本的.

測試腳本

fio -name=128k -filename=c:\io.speedtest -runtime=30 -direct=1 -bs=128k -rw=write -size=4g --iodepth=16 --thread
fio -name=8k -filename=c:\io.speedtest -runtime=30 -direct=1 -bs=8k -rw=randwrite -size=4g --iodepth=16 --thread
fio -name=8krw -filename=c:\io.speedtest -runtime=30 -direct=1 -bs=8k -rw=randrw -rwmixread=70 -size=4g --iodepth=16 --thread
fio -name=8kread -filename=c:\io.speedtest -runtime=30 -direct=1 -bs=8k -rw=read -size=4g --iodepth=16 --thread

注意不同的測試腳本分別對應測試:
128KB順序寫
8K 隨機寫
8K 隨機讀寫,並且70%的讀操作, 這個是數據庫常用的個處理
8K 順序讀 一般這個會到協議的頂峯. 如果這個到不了就可以改成128KB 的區塊大小

需要注意. windows 平臺不支持 多線程測試, 這裏是需要注意的. 

IOPS和帶寬數值越大越好. 太低的數值, 會帶來一些問題. 
注意實際測試中最好加大runtime時間和文件大小最好能夠擊穿raid卡的緩存或者是磁盤緩存 這樣測試結果纔是正確的.
