有效监控网络性能

There are lots of tips for improving your website performance. But even if you follow all of the advice, are you able to maintain an optimized site? And are you targeting the right pages? Matt Zeunert outlines an effective strategy for web performance optimization and explains the roles that different types of data play in it.

有很多关于 提高网站性能 的建议。但即使您遵循了所有建议，您能否维持一个优化的网站？您是否针对正确的页面？Matt Zeunert 概述了一种有效的网络性能优化策略，并解释了不同类型的数据在其中的作用。

There’s no single way to measure website performance. That said, the Core Web Vitals metrics that Google uses as a ranking factor are a great starting point, as they cover different aspects of visitor experience:

没有单一的方法来衡量网站性能。 也就是说，Google 使用的核心网络指标 作为排名因素 是一个很好的起点，因为它们涵盖了访客体验的不同方面：

• Largest Contentful Paint (LCP): Measures the initial page load time.
• 最大内容绘制 (LCP): 测量初始页面加载时间。
• Cumulative Layout Shift (CLS): Measures if content is stable after rendering.
• 累积布局偏移 (CLS): 测量内容在渲染后是否稳定。
• Interaction to Next Paint (INP): Measures how quickly the page responds to user input.
• 交互到下一个绘制 (INP): 测量页面对用户输入的响应速度。

There are also many other web performance metrics that you can use to track technical aspects, like page weight or server response time. While these often don’t matter directly to the end user, they provide you with insight into what’s slowing down your pages.

还有许多其他的 网页性能指标，您可以用来跟踪技术方面，比如页面重量或服务器响应时间。虽然这些通常对最终用户没有直接影响，但它们为您提供了有关什么导致页面变慢的洞察。

You can also use the User Timing API to track page load milestones that are important on your website specifically.

您还可以使用 用户计时 API 来跟踪在您的网站上特别重要的页面加载里程碑。

Synthetic And Real User Data #

合成与真实用户数据 #

There are two different types of web performance data:

有 两种不同类型 的网络性能数据：

• Synthetic tests are run in a controlled test environment.
• 合成测试 在受控测试环境中进行。
• Real user data is collected from actual website visitors.
• 真实用户数据是从实际网站访客收集的。

Synthetic monitoring can provide super-detailed reports to help you identify page speed issues. You can configure exactly how you want to collect the data, picking a specific network speed, device size, or test location.
