Understanding and Optimizing Mobile Page Performance and Jank
Effective mobile page performance requires identifying three jank types—screen tearing, frame drops, and long unresponsiveness—monitoring metrics such as response time, animation latency, idle time, and SM, understanding the CPU‑GPU rendering pipeline, and applying optimizations like hardware acceleration, transform‑based animations, reduced layout thrashing, task slicing, and GPU‑friendly techniques.
