问题
- 使用带有 10/100 Mbit/s 以太网端口的设备，我是否仍能验证 50 Mbit/s 光缆连接的速度，还是我需要 Gbit/s 连接？到目前为止，我认为是的，但 ISP 技术人员没有详细说明，而是回答了“否”。
- 我如何解释 speedtest-cli 结果（查看数据）？
- 我还发现我的网络提供商（即 ISP）仅提供 IPv6 链接。因此，我使用 DS-lite 进行 IPv4 隧道传输。我现在问自己，这是否也是导致我出现延迟问题的原因？
- 我怎样才能深入挖掘 ping 跳变的原因？
- 有没有更好的方法来调试速度问题？
背景故事
我有一个 50 Mbit/s 的光纤连接，但对服务非常不满意。在高峰时段，我“感觉”服务很慢，网页加载时间更长。
为了“证明”我写道这用 Python 编写的脚本。它使用 speedtest-cli 对法兰克福、都柏林、纽约和洛杉矶的服务器进行 ping 和上传和下载测试。它还使用 nmap 来验证我的网络中当前有多少台“机器”。这样我就知道消耗的流量是否可能来自观看 Netflix 的人。我将脚本安装为 cronjob，每小时在 Raspberry 3 上运行一次，只有一个 10/100 Mbit/s 以太网端口。

答案1
您的连接速度慢很可能是由于使用了不良的路由硬件，而不是 ISP 造成的。问题不在于 100MBit 端口，但由于这是一项旧技术，他可能认为您的路由硬件的处理器可能太慢，甚至无法执行基本的路由任务。要测试它，您可以将 PC 直接连接到光纤硬件，看看您的问题是否仍然存在，这是每个 ISP 首先建议的解决方案，您应该在寻找其他解决方案之前先尝试一下。那些人，尤其是光纤，可以非常准确地测试您的连接。
