    文章目录

    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

    • 1

    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/

    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'
