Full Page Caching is the most effective way to boost your website’s performance and scalability.

By default, WordPress builds every page dynamically. When a visitor requests a page, WordPress executes PHP code, runs multiple database queries, and assembles the content into an HTML file before sending it to the browser. This process consumes server resources (CPU and RAM) and takes time.

Full Page Caching completely changes this process. Instead of building the page from scratch for every visitor, RunCache generates a complete static HTML version of the page after the very first visit. This static file is then stored and served instantly to all subsequent visitors.

This has several benefits:

  • Drastically Faster Load Times: Serving a static file is exponentially faster than executing PHP and querying a database. This directly improves your Time to First Byte (TTFB).
  • Reduced Server Load: Minimizing PHP and database usage frees up server resources, allowing your site to handle much more traffic without slowing down.
  • Improved Scalability: Your website can easily serve thousands of concurrent visitors, as the server simply delivers lightweight, pre-built files.

Configuring Full Page Cache in RunCache

You can manage all Full Page Cache settings directly from your WordPress dashboard.

  1. Navigate to RunCache > Settings in your WordPress admin menu.
  2. Select the Page Cache tab.

Enabling/Disabling Full Page Cache

To activate or deactivate full-page caching, use the main toggle switch at the top of the page:

Cache Type Selection

RunCache offers four methods for storing page cache, each suited to different server configurations:

  1. NGINX Cache: This mechanism uses server-level caching to bypass application processing for faster delivery. It is optimized to provide improved performance for Nginx-powered websites. This option is only available on NGINX servers.
  2. NGINX FastCGI Cache: This high-performance caching method uses the ngx_cache_purge module to manage server-level storage. It offers superior speed while providing the precise control needed to purge specific URLs. This option is only available on NGINX servers.
  3. Redis Cache: This option uses Redis as a high-performance in-memory cache for your data. It is the ideal solution for high-traffic websites that require rapid cache access and support for cluster configurations.
  4. Cloudflare Cache: This enterprise-level solution leverages Cloudflare’s global CDN network to cache your content closer to your visitors. It features automatic cache management to ensure efficient delivery and reduced latency worldwide.
  5. LS Cache: This caching method uses LiteSpeed’s built-in server capabilities to store pages directly in memory or on disk. It completely bypasses PHP execution and database queries to deliver extremely fast response times. This option is only available on OpenLiteSpeed servers.
