写在开始：

• 博客简介：专注AIoT领域，追逐未来时代的脉搏，记录路途中的技术成长！
• 博主社区：AIoT机器智能, 欢迎加入！
• 专栏简介：记录嵌入式开发过程中使用到的工具集合。
• 面向人群：嵌入式工程师

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.
177/90400535/
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 20.0M    0     0  100 20.0M      0   190k  0:01:47  0:01:47 --:--:--  208k

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

Saving to: `lnmp1.8.tar.gz'

100%[===========================================>] 488,716,790 48.5M/s in 8.9s

6.3 speedtest

$ wget https://raw.github.com/sivel/speedtest-cli/master/speedtest.py
$ chmod a+rx speedtest.py
$ mv speedtest.py /usr/local/bin/speedtest
