1. 概述
简单总结了两种实用的嵌入式设备网速测试的方法：iperf和curl，这两种工具基本上都属于文件系统自带的指令。
2. 测试环境
- 测试设备：嵌入式Linux设备
- 测试场景：办公区
- 测试方法：连接远程服务器，测试网速
3. perf3
- 测试命令：
iperf3 -c xxx.xxx.xxx.xxx -p 5002 -i 1 -t 60000 -P 10
xxx.xxx.xxx.xxx，服务器IP
-i，指定打印间隔
-t，指定测试时间，单位s
-P，指定测试并行数，不添加默认为1个线程
-p，指定测试端口
-c，指定测试模式，-c客户端模式，-s服务端模式
- 测试结果：
/usrdata/QuecOpen # iperf3 -c xxx.xxx.xxx.xxx -p 5002 -i 1 -t 60000 -P 10

办公室网速大概 1.6Mbps左右。
4. curl
- 生成测试大文件：
dd if=/dev/urandom of=file1 bs=1M count=20
- 启动测试：
curl -u "user:name" -T file1 ftp://xxx.xxx.xxx.xxx/90400535/
- 测试结果：
/usrdata/QuecOpen # curl -u "user:name" -T file1 ftp://118.178.106.

使用curl实际传输文件平均速度为208kB/s
5. 总结
总结，使用curl、iperf测试结果 一致 ，iperf：1.6Mbps，curl：208KB/s，等价208*8=1.6Mbps
6. 其它网络测速方法：
6.1 wget
测试下行速度。
wget http://soft.vpser.net/lnmp/lnmp1.8.tar.gz
