SuperHertz Cache Preloader

SuperHertz Cache Preloader is a powerful companion plugin for LiteSpeed Cache that ensures your pages, posts, products, and custom post types are always pre-warmed in the cache — so no visitor ever hits a cold, uncached page.

Why You Need a Cache Preloader

LiteSpeed Cache is incredibly fast, but it only caches pages after the first visitor requests them. 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.
