That first visitor gets a slow, uncached response. This plugin solves that by proactively crawling every public URL on your site to build the cache before any real visitor arrives. #### Key Features * **Automatic Site Crawling** — Discovers and warms all public pages, posts, products( WooCommerce), and custom post types automatically. * **Parallel Processing Engine** — Multi-threaded cURL engine processes multiple URLs simultaneously for faster warm-up times. * **Sequential Mode** — Optional single-threaded mode for shared hosting or resource- constrained environments. * **Smart Throttle Guard** — Automatically reduces concurrency when server RAM exceeds 85% or CPU load exceeds 5.0 to protect your server. * **TTFB Latency Tracking** — Monitors Time To First Byte per URL and flags slow pages (> 2.0s). * **Server Load Monitoring** — Real-time dashboard cards showing Memory Footprint, CPU Load, OpCache status, and Database Query metrics. * **Configurable Concurrency** — Set parallel thread count from 2x to 25x based on your server capacity. * **Adjustable Rest Delay** — Configure pause between requests (0ms to 500ms) to balance speed vs. server load. * **Scheduled Cron Warming** — Set automatic daily, twice-daily, or hourly cache warming with custom start times. * **Manual One-Click Warming** — Trigger a full cache warm-up from the admin dashboard at any time. * **Per-URL Debug Logging** — Detailed console showing HTTP status, TTFB, cache HIT/MISS status, and LiteSpeed headers for every URL. * **Auto Log Clearing** — Debug logs automatically clear on each new run for clean diagnostics. * **Smart Cache Bypass** — Automatically excludes cart, checkout, account, and dashboard pages from warming. * **Admin Bar Protection** — Prevents WordPress Admin Bar from being cached for non-admin users (vendors, customers, guests). * **ESI-Aware Crawling** — Sends proper ESI and cache-control headers during warm- up requests. * **V8 Module Pre-Warming** — Injects `modulepreload` hints for JavaScript bundles to eliminate client-side cold starts. * **WP-CLI Support** — Run cache warming from the command line with `wp superhertz- cache-preloader warm`. * **Full-Width Admin Panel** — Clean, modern dashboard UI that uses your full screen width. #### How It Works 1. The crawler engine queries WordPress for all published pages, posts, products, and custom post types. 2. It builds a URL queue and sends HTTP requests (with LiteSpeed-compatible headers) to each URL. 3. LiteSpeed Cache intercepts these requests and stores the rendered pages in its cache. 4. When a real visitor arrives, they get the pre-cached version instantly. #### Server Requirements * LiteSpeed Web Server (OpenLiteSpeed or LiteSpeed Enterprise) * [LiteSpeed Cache plugin](https://wordpress.org/plugins/litespeed-cache/) installed and activated * PHP 7.4 or higher * WordPress 5.8 or higher ## Installation 1. Upload the `superhertz-cache-preloader` folder to the `/wp-content/plugins/` directory, or install directly through the WordPress plugin screen. 2. Activate the plugin through the ‘Plugins’ screen in WordPress. 3. Navigate to **Settings LiteSpeed Warmer** in your WordPress admin. 4. Configure your preferred concurrency level, rest delay, and cron schedule. 5. Click **Run Cache Warm-Up** to perform your first manual warming. ## FAQ ### Does this plugin replace LiteSpeed Cache? No. This plugin is a **companion** to LiteSpeed Cache. You must have LiteSpeed Cache installed and activated. This plugin simply ensures the cache is pre-populated so no visitor ever hits a cold page. ### Will this overload my server? No. The plugin includes a **Smart Throttle Guard** that automatically reduces concurrency when RAM usage exceeds 85% or CPU load exceeds 5.0. You can also switch to sequential mode or increase the rest delay between requests for shared hosting environments. ### Does it work with WooCommerce? Yes. The crawler automatically discovers and warms all WooCommerce product pages, shop pages, and category archives. ### Can I exclude certain pages from warming? Yes. Cart, checkout, account, and dashboard pages are automatically excluded since they contain dynamic, user-specific content that should never be cached. ### Does it support WP-CLI? Yes. You can trigger a cache warm-up from the command line: ``` wp superhertz-cache-preloader warm ``` ### What is the V8 Module Pre-Warming feature? It injects `` tags in the page head for JavaScript bundle files, allowing browsers to pre-parse and compile JS modules before they are needed— reducing client-side startup time. ### Why is the Admin Bar being cached for guests? This plugin automatically strips the WordPress Admin Bar for all non-administrator users (vendors, customers, subscribers, and guests) to prevent it from being cached by LiteSpeed and served to the wrong users. ## Reviews ![](https://secure.gravatar.com/avatar/411216c9853ecd7fc07a1f63a5229b536241d234e489b0c580b0e9d0676749a9? s=60&d=retro&r=g) ### 󠀁[Gamechanger](https://wordpress.org/support/topic/gamechanger-18/)󠁿 [Byron Iniotakis](https://profiles.wordpress.org/orloxgr/) August 7, 2026 It can make your website instant if you use litespeed.
