Optimization of T7 Browser Kernel Cache Mechanism in Baidu App

The Baidu App’s T7 browser kernel team optimized its HTTPCache and MemoryCache by enabling main‑document and file‑protocol caching, introducing a fixed‑size LRU cleanup, providing custom preload/query APIs, and leveraging NoState Prefetch, which together cut page‑load latency by over 30 % and markedly improve user experience.

Analysis of Glide Image Loading Cache Mechanisms on Android

The article dissects Glide’s five‑level caching system—active resources, memory cache, resource and data disk caches, and network cache—explaining how active weak references feed the LRU memory cache, how DiskCacheStrategy governs transformed and raw data storage, and how I/O and network tasks run on separate executors while network responses are cached before delivery.
