尽管 YouTube 每月有超过十亿用户的规模，但网页性能测试所遵循的核心原则同样适用于您自己的网站。在本视频中，您将了解我们如何衡量网页加载速度，以及如何对测试进行插桩测试，以提高速度。我们将了解两种前端性能测试方法：使用客户端插桩进行真实用户监控 (RUM)，以及使用 WebPagetest 进行合成测试。

The core of their testing involves measuring page load speed and instrumenting tests for optimization. They employ two primary methodologies: Real User Monitoring (RUM), which utilizes client-side instrumentation to gather data from actual users, and synthetic testing using WebPagetest, to simulate user experiences and assess performance in a controlled setting.\n"]]
