WeChat mini program startup time is slowed by large main package sizes and complex initialization. You can optimize first launch performance by reducing main package volume, simplifying startup logic, applying sub-packaging strategies, and implementing skeleton screens for faster initial rendering.

Scrolling jank and frame drops in a WeChat mini program are caused by excessive setData updates and inefficient WXML rendering. You can fix runtime rendering performance by reducing setData call frequency, optimizing data granularity, and simplifying WXML node structures.

White screens in WeChat mini programs occur when initial rendering is blocked by heavy startup loading or complex page structures. You can prevent white screens by optimizing first-screen rendering strategies, applying sub-packaging, and implementing skeleton screens to improve perceived loading speed.

WeChat mini program memory leak risks stem from inefficient resource loading and unmanaged data during page switching. You can identify and resolve memory risks by analyzing long list rendering patterns, optimizing page lifecycle management, and following structured diagnostic checklists.

The best way to reduce WXML rendering complexity is to minimize WXML node quantities and optimize page switching and long list rendering. Applying an actionable WXML checklist helps convert diagnostic bottlenecks into direct engineering tasks for improved rendering performance.
