有许多服务可免费用于测试您的 Internet 连接速度^{(test your Internet connection speed)}。有一些网站由HTML5提供支持，以前由Adob​​e Flash提供支持；有适用于各种平台的独立应用程序以及可以帮助您实现相同结果的浏览器扩展。但是，建议用户坚持使用在其地理区域内渗透了更多服务器的客户端以获得最佳结果。因此^(Hence)，建议使用各种服务，例如Netflix的^(Netflix)Fast和Ookla的Speed Test。然而，像谷歌浏览^{(Google Chrome)}器这样的网络浏览器，由Chromium附带一个称为 NetworkInformation API的内置^{(NetworkInformation API)}API，可帮助您找到有关网络的相关信息。

^{(Check Internet Connection Speed)}使用Chrome检查 Internet 连接速度

要使用Google Chrome^{(Google Chrome)}查找您的网络连接统计信息，我们将介绍两种方法 -

1. 使用 Chrome 开发工具。
2. 使用GitHub 上^(GitHub)托管的网络信息 API 示例^{(Network Information API Sample)}。

1] 使用 Chrome 开发工具^{(1] With Chrome Dev Tools)}

确保^(Make)您运行的是Google Chrome v65 或更高版本。选择Google Chrome^{(Google Chrome)}窗口右上角由三个垂直点表示的菜单按钮。然后点击 关于。^(About.)

验证后，首先导航到Google Chrome^{(Google Chrome)}上的任何网页，然后按键盘上的 F12 按钮。^(F12 )

在名为 Console 的选项卡下， ^(Console, )输入以下内容并按 Enter-

navigator.connection

您将在与上图中的 sh9wn 相同的控制台窗口中看到输出。

此处，下行链路 ^(downlink )的值表示您计算机的实际下载速度，单位为 Mbps。

rtt 等值 ^(rtt )表示 Ping， 有效类型 ^{(effective type )}表示基于您已达到的下载速度的连接类型。

提示^(TIP)：您还可以使用此 Google 工具^{(this Google tool)}测试您的互联网速度。

2] 使用 GitHub 上托管的网络信息 API 示例^{(2] With Network Information API Sample hosted on GitHub)}

Chromium 的开发人员在GitHub 上^(GitHub)托管了一个页面，其中包含网络信息 ^{(network information )}API的示例 。

只要您访问此处的链接，您将在具有^(here)实时连接^{(Live Connection)}输出的页面上获得相同的结果。

因此，您现在可以在不依赖任何第三方服务的情况下检查您的连接速度。

How to check your Internet Connection Speed using Google Chrome

There are a number of serviсes that are available for free to test your Internet connection speed. There are websites powered by HTML5 and were previously powered by Adobe Flash; there are standalone applications for various platforms as well as browser extensions that would help you achieve the same results. However, a user is advised to stick to a client whose more servers are penetrated across their geographical region to get the best results. Hence, various services like Fast by Netflix and Speed Test by Ookla are advised to be used. However, web browsers like Google Chrome, that are powered by Chromium come with an inbuilt API called the NetworkInformation API that will help you find relevant information about your network.

Check Internet Connection Speed using Chrome

To find your network connection statistics using Google Chrome, we will cover two methods-

1. With Chrome Dev Tools.
2. With Network Information API Sample hosted on GitHub.

1] With Chrome Dev Tools

Make sure that you are running Google Chrome v65 or later. Select the menu button denoted by three vertical dots on the top right corner of the Google Chrome window. And then click on About.

Once verified, start by navigating to any web page on Google Chrome and hit the F12 button on your keyboard.

Under the tab named as Console, type in the following and hit Enter-

navigator.connection

You will see the output in the same console window as sh9wn in the image above.

Here, the value of the downlink denotes the actual download speed of your computer in Mbps.

Values like rtt denote the Ping, effective type denotes the connection type based on the download speed that you have achieved.

TIP: You can also test your internet speed using this Google tool.

2] With Network Information API Sample hosted on GitHub

The developers for Chromium have hosted a page on GitHub with a sample for the network information API.

Just as soon as you visit the link here,  you will get the same results on a page with Live Connection output.

Thus you can now check your connection speed without relying on any third party services.
