android存儲讀寫測試工具-fio

一.工具下載下傳并編譯

1.wget http://brick.kernel.dk/snaps/fio-2.2.5.tar.gz

2.tar -zxvf fio-2.2.5.tar.gz

3.cd fio-2.2.5

4.因為我們要在android中運作，是以我們需要安裝交叉編譯工具

sudo apt-get install gcc-arm-linux-gnueabihf

5.編譯代碼，指定arm運作平台，編譯工具為arm-linux-gnueabihf-gcc，并且需要靜态編譯

./configure --cpu=arm --cc=arm-linux-gnueabihf-gcc --build-static --disable-shm

make

6.編譯完成後會生成fio可執行程式我們把它push到手機中

adb push fio /system/bin/

二.測試指令

随機讀

fio -filename=/data/test_rand -direct=1 -iodepth 1 -thread -rw=randread -ioengine=psync -bs=1M -size=1G -numjobs=5 -group_reporting -name=mytest
           

随機寫

fio -filename=/data/test_rand -direct=1 -iodepth 1 -thread -rw=randwrite -ioengine=psync -bs=1M -size=1G -numjobs=5 -group_reporting -name=mytest
           

順序寫

fio -filename=/data/test_ordwrite -direct=1 -iodepth 1 -thread -rw=write -ioengine=psync -bs=1M -size=1G -numjobs=5 -group_reporting -name=mytest
           

順序讀

fio -filename=/data/test_ordread -direct=1 -iodepth 1 -thread -rw=read -ioengine=psync -bs=1M -size=1G -numjobs=5 -group_reporting -name=mytest
           

三.日志解析

四.配合腳本做性能測試

五.問題彙總

運作報錯1：

xxxx:/ # fio -filename=/tmp/test_randread -direct=1 -iodepth 1 -thread -rw=randread -ioengine=psync -bs=16k -size=30G -numjobs=10 -runtime=600 -group_reporting -name=mytest

shmget: Function not implemented

error: failed to setup shm segment
           

指的編譯環境時需要加上：--disable-shm

./configure --cpu=arm --cc=arm-linux-gnueabihf-gcc --build-static --disable-shm
