交叉编译iperf测试arm开发板上wifi模块的网络流量速度

1.在pc机端安装iperf软件
luther@gliethttp:~$ sudo apt-get install iperf
2.交叉编译iperf到arm开发板上
luther@gliethttp:~$ wget http://downloads.sourceforge.net ... =1207626803&big_mirror=0
luther@gliethttp:~$ tar zxvf iperf-2.0.4.tar.gz
luther@gliethttp:~/iperf-2.0.4$ ./configure --help
luther@gliethttp:~/iperf-2.0.4$ ./configure --host=arm-linux
luther@gliethttp:~/iperf-2.0.4$ vim config.h
修改如下内容：可以通过./configure查看正常编译的配置信息,将差异修改到arm交叉编译生成的config.h中
...
#define HAVE_MALLOC 0          改为 #define HAVE_MALLOC 1
/* #undef HAVE_QUAD_SUPPORT */  改为 #define HAVE_QUAD_SUPPORT 1
#define malloc rpl_malloc    改为 /* #undef malloc */
luther@gliethttp:~/iperf-2.0.4$ make -j4 //我的pc为双核
luther@gliethttp:~/iperf-2.0.4$ ll src/iperf
-rwxr-xr-x 1 luther luther 75K 2008-11-25 16:07 src/iperf
这样我们运行到arm上的iperf程序就编译成功了,将它拷贝到arm板子上.
1.在pc上以服务器模式启动iperf
luther@gliethttp:~$ iperf -s
2.将交叉编译的iperf拷贝到arm开发板上
/ # tftp -r iperf -g 192.168.100
/ # chmod 755 iperf
/ # ./iperf -c 192.168.2.65 -i 5 -t 60
//192.168.2.65是我的pc端ip地址
//-i 5表示arm板子上启动的client每5s打印一下速度信息;
//-t 60表示测试60s;
//默认使用tcp传输
/ # ./iperf -c 192.168.2.65 -i 5 -t 60

在pc端经过60s之后,打印最终log如下：
luther@gliethttp:~$ iperf -s

上面
192.168.2.65为以服务器模式运行的iperf所在pc的ip地址
192.168.2.101为wifi通过dhcpcd eth0动态获取的ip
