PHP Caching Techniques: Page Cache, Data Cache, and File Cache

This article explains why PHP caching is essential for web performance and details three main techniques—page caching with output buffering, data caching using extensions like Memcached or APCu, and file caching with file I/O functions—plus best practices for updates, expiration, and avoiding cache penetration.

Analysis of Linux mmap File Read Process and Page Fault Handling

The article walks through Linux’s mmap file‑read workflow—from the kernel entry point and VMA creation, through page‑fault handling that allocates pages and invokes synchronous or asynchronous readahead, to munmap’s unmapping steps and the deferred file‑cache reclamation mechanisms.

Linux Kernel File Cache Mechanism: In-Depth Analysis of Read/Write Processes and Pre-reading Algorithm

The article thoroughly explains Linux kernel file cache, detailing how read() and write() operations traverse VFS to the block layer, the adaptive read‑ahead algorithm that pre‑loads sequential pages, the internal functions such as generic_file_buffered_read and ondemand_readahead, and outlines write handling and future topics on mmap and cache reclamation.
