Description
Warmer helps maintain optimal site performance by automatically visiting pages to pre-populate your cache. Instead of having your visitors experience slower initial page loads while the cache builds, this plugin ensures your cache stays warm.
The plugin works by intelligently crawling your site’s content based on your configuration. It can warm cache for posts, pages, archives and media files on a schedule you define. This proactive approach means your visitors will always experience fast page loads since the cache is pre-built.
Our crawler is designed to be lightweight and respectful of your server resources. You can fine-tune the crawling behavior by adjusting request delays, timeouts, and concurrent connection limits. This ensures the cache warming process won’t impact your site’s performance.

FAQ
-
Which caching plugins are supported?
-
The plugin works with all major WordPress caching plugins including WP Super Cache, W3 Total Cache, WP Rocket, and LiteSpeed Cache. The cache warming process is cache-plugin agnostic and will work with any solution that creates cached pages when URLs are visited.
-
How often does the cache warming occur?
-
By default, the plugin runs every 6 hours but this can be customized in the settings to run hourly, twice daily, or daily. Choose a frequency that balances cache freshness with server load. For most sites, twice daily is a good starting point.
-
Will this slow down my site?
-
No, the cache warming process is designed to run in the background with minimal impact on site performance. You can configure the request delay and timeout settings to optimize the crawling process for your server environment. The crawler respects your server’s resources and can be paused at any time.
-
How can I monitor the cache warming process?
-
The plugin provides detailed logs of all cache warming activities. You can view real-time crawling status, download log files for analysis, and use the debug tools to test various components. The logs show which URLs were successfully cached and any issues that were encountered.
-
Can I exclude certain URLs from cache warming?
-
Yes, the plugin allows you to selectively enable/disable cache warming for different types of content including posts, pages, category archives, tag archives, and media attachments. This gives you fine-grained control over which parts of your site are included in the cache warming process.
-
What should I do if I encounter issues?
-
- Check the debug tools section to verify system compatibility
- Review the logs for any error messages
