For sites concerned with high traffic, speed for logged-in users, or dynamic pageloads, a high-speed and persistent object cache is a must. You also need something that can scale across multiple instances of your application, so using local file caches or APC are out.
Redis is a great answer, and one we bundle on the Pantheon platform. This is our plugin for integrating with the cache, but you can use it on any self-hosted WordPress site if you have Redis. Install from <a href="https://wordpress.org/plugins/wp-redis/" rel="ugc">WordPress.org</a> or <a href="https://github.com/pantheon-systems/wp-redis" rel="nofollow ugc">Github</a>.
It’s important to note that a persistent object cache isn’t a panacea – a page load with 2,000 Redis calls can be 2 full seconds of object cache transactions. Make sure you use the object cache wisely: keep to a sensible number of keys, don’t store a huge amount of data on each key, and avoid stampeding frontend writes and deletes.
Go forth and make awesome! And, once you’ve built something great, <a href="https://github.com/pantheon-systems/wp-redis/issues" rel="nofollow ugc">send us feature requests (or bug reports)</a>.

Do a little dance

Works like a charm and significantly improves the page rendering speed for my website. Play nice with https://wordpress.org/plugins/batcache/. These two allow me to get literally light speed performance for static pages.

Works like a charm!

FlynCache Purge is a professional, lightweight WordPress plugin that automatically detects your server’s cache configuration and intelligently manages cache purging across multiple cache layers. Whether you’re running Nginx with FastCGI Cache, Redis Object Cache, LiteSpeed server cache, Cloudflare CDN, or any other CDN — FlynCache Purge handles it all from one unified interface.
🚀 Key Features:
<ul>
<li>Auto Server Detection — Automatically detects your web server (Nginx, Apache, LiteSpeed, OpenLiteSpeed) and available cache systems</li>
<li>Auto Cache Path Detection — Scans your server for Nginx FastCGI cache directories and Redis connections automatically</li>
<li>Nginx FastCGI Cache Purge — Purges Nginx FastCGI cache by file removal, supporting multiple directory structures (Webinoly, EasyEngine, ServerPilot, and custom configs)</li>
<li>Redis Object Cache Purge — Connects to Redis via phpredis extension for full database flush or selective key purge</li>
<li>LiteSpeed Cache Purge — Integrates with LSCWP plugin API, LiteSpeed purge headers, and filesystem-based cache clearing</li>
<li>Cloudflare Cache Purge — Uses Cloudflare API v4 to purge entire zones or specific URLs with chunked request support</li>
<li>Custom CDN Support — Compatible with KeyCDN, StackPath, BunnyCDN, Fastly, Sucuri, CloudFront, and any CDN with HTTP purge API</li>
<li>Smart Auto-Purge — Automatically purges cache on: post publish/update/delete, new comments, theme switches, plugin changes, widget updates, customizer saves, nav menu changes, and more</li>
<li>Related URL Purge — When a post is updated, also purges category, tag, author, archive, feed, and date archive pages</li>
<li>Manual Purge — One-click purge all caches or purge specific URLs manually</li>
<li>Recommended Settings — Plugin analyzes your server and suggests optimal configuration</li>
<li>Connection Testing — Built-in test buttons for Redis and Cloudflare connectivity</li>
<li>Export/Import Settings — Backup and restore your configuration</li>
<li>Lightweight & Fast — Minimal footprint, only loads what’s needed, zero frontend impact</li>
</ul>
<h3>External Services</h3>
This plugin optionally connects to the following external services. These services are only used when you explicitly enable and configure them in the plugin settings. No data is sent unless you opt in.
Cloudflare API v4
This service is used to purge Cloudflare CDN cache when you enable the Cloudflare cache purge feature. It is needed to send cache purge requests for your Cloudflare zones.
<ul>
<li>What data is sent: Your Cloudflare API token and Zone ID (stored in your WordPress database) are used to authenticate purge requests. No user data or content data is transmitted.</li>
<li>When data is sent: Only when you manually purge cache or when auto-purge triggers and Cloudflare is enabled.</li>
<li>Where data is sent: https://api.cloudflare.com/client/v4/</li>
<li>Terms of Service: https://www.cloudflare.com/terms/</li>
<li>Privacy Policy: https://www.cloudflare.com/privacypolicy/</li>
</ul>
LiteSpeed Admin API (optional)
If configured, the plugin can send purge requests to a LiteSpeed Admin API endpoint. This is entirely optional and only used if you provide the Admin URL and API key in settings.
<h3>Why FlynCache Purge?</h3>
Managing cache across multiple layers (server cache, object cache, CDN cache) is complex. Each cache has its own purge method, API, and configuration. FlynCache Purge unifies all cache management into a single, intelligent interface that auto-detects your setup and handles purging automatically — so you never have to worry about stale content again.
<h3>Supported Cache Types</h3>
<ul>
<li>Nginx FastCGI Cache — File-based cache used by Nginx with PHP-FPM (supports Webinoly, EasyEngine, ServerPilot, and custom configs)</li>
<li>Redis Object Cache — Via phpredis extension, supports host/port/unix socket, authentication, and database selection</li>
<li>LiteSpeed Cache — Server-level cache + LSCWP plugin integration</li>
<li>Cloudflare CDN — API token-based cache purge with zone support</li>
<li>Custom CDN — Any CDN with HTTP purge API (KeyCDN, StackPath, BunnyCDN, Fastly, etc.)</li>
</ul>
