LMbench 3.0移植到Android并测试内存带宽

LMbench是个可移植的，用于评价系统综合性能的多平台开源benchmark，能够测试包括文档读写、内存操作、进程创建销毁开销、网络等性能。通过以下步骤操作，即可将LMbench移植到Android上。

  • 下载LMbench源码

下载地址http://sourceforge.net/projects/lmbench/
也可在本站下载

  • 修改LMbench代码

1.解压缩到指定的目录，保证最终的目录如下：

├── lmbench3/

│        ├── jni/

│            ├── doc/

│            ├── result/

│            ├── scripts/

│            ├── src/

│            ├── ACKNOWLEDGEMENTS

│            ├── CHANGES

│            ├── COPYING

│            ├── COPYING-2

│            ├── hbench-REBUTTAL

│            ├── Makefile

│            ├── README

2.修改“src/bench.h”的38行，40行，注释掉“#include <rpc/rpc.h>”，“#include <rpc/types.h>”，然后添加如下定义

#ifndef S_IREAD 
#define S_IREAD S_IRUSR
#endif

#ifndef S_IWRITE
#define S_IWRITE S_IWUSR
#endif

3.添加根目录下面Android.mk，jni/目录下面内容如下：
