Smoothness Monitoring Practices in Baidu App: Concepts, Industry Solutions, and Implementation

To ensure user delight beyond basic stability, Baidu App adopts end‑to‑end smoothness monitoring that measures frame‑rate, frame length, and dropped frames using VSync‑based Choreographer callbacks, Looper timestamps, and selective stack sampling, while balancing visual richness on diverse devices and interpreting metrics across varied usage scenarios.

Performance Optimization and Frame‑Rate Testing for iOS Mobile Client Dynamic Layout

The article outlines iQIYI’s iOS dynamic‑layout architecture, recommends CADisplayLink for frame‑rate checks and TimeProfiler for deep analysis, then details a two‑phase optimization workflow—eliminating main‑thread bottlenecks (e.g., string formatting, image loading, view hierarchy changes) and reducing off‑screen rendering and layer blending through layer tricks, caching, and asset adjustments—to achieve smoother UI on low‑end devices.
