Speed monitoring collects real user data from PCs and mobile devices to track core performance metrics such as CLS, FCP, FID, LCP, TTFB, and INP in real time. It includes webpage monitoring with HTML page analysis and three-color performance ratings, and adaptive performance optimization that collects anonymized client-side data from error and CAPTCHA pages for analysis. Data is collected via a JavaScript (JS) script that supports automatic or manual integration. For users outside the Chinese mainland, data is sent to Singapore. Only network metrics are recorded, and no private user information is collected.
