Understanding WordPress Caching Architecture

Caching is the single most effective technique to reduce server load and improve Google Core Web Vitals. Here is how different caching layers interact on your server.

📄 Page Caching

Saves dynamic PHP-rendered pages into pre-built static HTML files on disk or memory. Subsequent visitors download the static HTML instantly without querying MySQL or executing PHP scripts.

🗄️ Object Caching (Redis/Memcached)

Stores database query results in RAM. Essential for highly dynamic websites like WooCommerce stores, membership platforms, and online courses where static HTML caching cannot be applied to logged-in users.

⚡ Script Execution Delaying

Postpones heavy JavaScript execution (such as Google Analytics, chat widgets, and pixels) until the user physically interacts with the page (mouse movement or touch), drastically improving INP scores.
