Speed monitoring provides webpage monitoring and adaptive performance optimization. Webpage monitoring collects real user data from PCs and mobile devices to monitor core performance metrics in real time, such as Cumulative Layout Shift (CLS), First Contentful Paint (FCP), First Input Delay (FID), Largest Contentful Paint (LCP), Time to First Byte (TTFB), and Interaction to Next Paint (INP). It supports HTML page analysis and a three-color performance rating system: green, yellow, and red. Data is collected by a JavaScript (JS) script that can be integrated automatically or manually. For users outside the Chinese mainland, this data is sent to Singapore. Only network metrics are recorded, and no private user information is collected. Adaptive performance optimization dynamically inserts an anonymized JS script into specific error and CAPTCHA pages. The script collects client-side performance data and sends it to a data center for processing and analysis.
