簡介

bonnie++ 是一套用來測試硬碟驅動程式及檔案系統效能的 benchmark，你可以決定那些測試是重要的，並且用它來比較兩個相異系統的差別。作者並不想將這些測試結果導向一個單一數字，因為他認為單一數字對比較這些東西並沒有什麼幫助。

安裝方法

sudo apt-get install bonnie++

指令

 bonnie++         [-d         dir]         [-s         size(Mb)[:chunk-size(b)]]         [-n         num-
 ber-to-stat(*1024)[:max-size[:min-size][:num-directories]]] [-m machine-name]  [-r  ram-size-in-Mb]  [-x
 number-of-tests] [-u uid-to-use:gid-to-use] [-g gid-to-use] [-q] [-f] [-b] [-p processes | -y]

-d 要測試的目錄
-s 測試的檔案大小(MB)
-n 測試的檔案數(Byte)
-m 機器的名稱，自行命名，只會顯示在螢幕上，不影響結果
-r 指定記憶體大小(MB)
-x 測試次數
-u 你所要使用的 user-id，不建議使用 root
-g 你所要使用的 group-id
-q 安靜模式，只會顯示結果，其它額外的訊息會被隱藏
-f 快速模式，會跳過 per-char IO 測試
-b 不要寫入緩衝，fsync (即時寫入)
-p 有多少的 processes 要來服務 semaphores
-y 在每次測試前等待 semaphore
