For mobile devices, how to avoid loading delays caused by triggering large network requests?

When mobile applications or web pages need to handle a large number of network requests, the core of avoiding loading delays lies in optimizing resource size and request efficiency. Typically, strategies such as resource compression, request merging, and on-demand loading can effectively reduce network transmission volume and the number of requests, thereby lowering latency. Resource compression: Compress images and CSS/JS files, such as using WebP format images and code minification to reduce the size of individual resources; apply gzip/brotli compression to text-based resources (e.g., API responses) to further reduce the amount of transmitted data. Request merging: Combine multiple independent small requests (such as multiple API calls) into a single batch request to reduce the number of HTTP/HTTPS handshakes, which is particularly suitable for scenarios with strong data关联性. Lazy loading: Delay the loading of non-first-screen content (such as images and list items visible after scrolling), and only initiate requests when triggered by user actions, reducing network pressure during the initial loading phase. In daily optimization, you can first use browser developer tools (such as the Network panel) to detect request sizes and quantities, prioritizing handling resources exceeding 100KB or duplicate requests; for image resources, it is recommended to combine responsive images (srcset) with progressive loading to balance image quality and loading speed, enhancing the mobile user experience.
