![1GBps 端口速度是多少?](https://linux22.com/image/1414427/1GBps%20%E7%AB%AF%E5%8F%A3%E9%80%9F%E5%BA%A6%E6%98%AF%E5%A4%9A%E5%B0%91%EF%BC%9F.png)
我有一个问题,关于如何测量我服务器的下载速度。基本上,我在 Namecheap 有一个专用服务器,我购买了 1GBps 端口速度。(不是广告)。但当我运行时,speedtest-cli
我从未获得超过 300 Mbits/s 的速度。但我看到论坛上有人将 IP 达到 900 Mbits/s。而且服务器speedtest-cli
距离只有 45 公里。
我和他们讨论了这个问题,他们说测量下载速度的最佳方法是使用iperf
。他们得到了以下结果:

但事实是,当人们下载东西时,他们从来不会打开几个端口来下载。为什么我的服务器在同一个测试中与其他服务器不匹配。似乎有些不对劲。有人能告诉我他们提供的数据是否证明我的服务器是 1GBps?还是我被骗了?

答案1
您购买了一台带有千兆以太网端口的机器。这意味着此时的带宽为 1 gbps。这是合并进出服务器的所有流量的带宽。
你观察到的 300mbps 至少证明该机器具有 1gbps 以太网连接;因为下一个最高链接速度(假设有线以太网)是 100mbps,您已经超过了这个速度。除此之外,没有什么可说的。
您发布了他们的结果,但没有发布您自己的结果;您是否也尝试了多个 Speedtest 服务器 ID?而且,这可能是一件愚蠢的事情,但请确保您是从服务器运行 speedtest-cli,而不是无意中从本地计算机运行它。
您提到 speedtest-cli 根据 ping 时间来选择服务器。Ping 时间表示延迟,而不是带宽。Speedtest 服务器和您的服务器之间的带宽小于 1gbps 是合理的。您可能希望有多个速度测试服务器同时进行带宽检查,然后将它们全部加在一起;这就是他们执行的测试。
请记住,1gbps 端口速度主要帮助多个用户同时使用您的网站而不会互相影响,因为单个用户不太可能获得 1gbps 的持续服务器连接。单台服务器的 Speedtest 不是完成这项工作的合适工具。
顺便说一句,如果您的服务器运行的是 Linux,您可以直接验证以太网链接速度。首先查看ifconfig
接口名称(通常是 eth0 或类似名称),然后使用ethtool
显示有关接口的信息,其中包括硬件链接速度。
