Mirasvit Full Page Cache Warmer Magento 2 Extension Review

Caching is among the most reliable tools for making every website faster, and Full Page Cache is the most effective sort of cache. Although Magento 2 contains this cache type, there is still an issue with frequently cleared cache data that happens when someone makes changes within your store, mainly to categories or product pages. Besides, the cache can be cleared by lifetime: usually, it happens every X hours. As a result, the default FPC solution doesn’t provide maximum performance. Luckily, you can easily solve this problem with the help of the Mirasvit Full Page Cache Warmer Magento 2 extension. The tool is designed to prevent your store from slowdowns caused by rare cache updating. The extension monitors pages of your ecommerce website and refreshes cache if it is cleared. Thus, all your visitors get the highest page load speed and the best user experience. Otherwise, the number of orders and your revenue might decrease since slow performance can lead to the disappointment of potential buyers.

By default, page cache warmer crawls uncached pages and adds them to cache, which improves a website’s page loading speed. Mirasvit’s tool brings an intelligent robot that monitors the status of store pages and visits those which cache was cleared to warm them. You can configure the extension right after installation, and it will work automatically, doing everything in the background. 

As a result, your web store becomes much faster, and the latest page versions are always kept in the cache. Mirasvit Full Page Cache Warmer for Magento 2 works with product, category, layered navigation, and CMS pages. Besides, you increase your website’s ranking in the Google search results.

Let’s have a look at the Magento 2 cache warmer extension’s backend first and then describe its functionality.


You can view and manage all warmed pages of your website on a separate grid under System -> Page Cache Warmer -> Pages in the Magento backend. The Pages grid contains 14 columns in total:

  • checkbox,
  • ID,
  • Status (Cached, Pending, or Uncacheable),
  • URI,
  • Page Type,
  • Popularity,
  • Applied Warm Rules, 
  • Unsuccessful attempts,
  • Vary Data, 
  • Created At (GMT), 
  • Updated At (GMT), 
  • Cached At (GMT), 
  • Flush Discovered At (GMT),
  • and Action (you can warm or clean cache here, as well as remove the page from the grid).

Filtering options are available for each column except checkbox, Status, Vary Data, and Action. Besides, you can specify how many raws are displayed per page, as well as generate pages.

As for the cache warmer jobs, they are gathered on a grid under System -> Page Cache Warmer -> Jobs. The grid includes 11 columns: checkbox, ID, Priority, Filter, Info (displays execution time), Status, Created At, Updated At, Started At, Finished At, and Action (Run Job, Delete). Checkbox, Filter, Info, Status, and Action do not offer filtering options.

The full page cache Magento 2 module enables users to set up rules for warming pages. Existing rules can be viewed on a grid under System -> Page Cache Warmer -> Warm Rules. The Warm Rules grid shows an ID, name, status, and priority of each rule. It is possible to edit or delete particular rules from the Action column. 

If you want to add a new page warner rule, you need to set its setting in three sections: General Information, Page Conditions, and Request Modificators. First, create a name for your new rule, set its status as active or inactive, and define its priority.

Next, you can choose rule conditions or conditions combination based on various page attributes.

The last section here lets you specify HTTP headers.

Furthermore, the Magento 2 Full Page Cache Warmer extension provides page cache efficiency reports. The reports allow admin users to track page caching performance that affects page loading speed on your website.

Now, let’s have a look at the Mirasvit Full Page Cache Warmer settings available on the Configuration page. They are divided into 5 sections: General Settings, Performance, Extended Settings, FPC hole punch, and Debug.

In General Settings, first, enable or disable the extension. Then, you can specify URL patterns of pages that should be excluded from the warming process, as well as enter appropriate regular expressions for defining ignored user agents.

The Performance settings enable you to choose the number of threads (concurrent requests to store), specify a delay between requests and the maximum job run time, and create a job schedule (use only cron expression here).

Extended Settings allow you to enable/disable collecting statistics and specify the limit for the average system load in percent that should stop warmer job running. Next, you can set the warmer limit (number of URLs in the cache) and forbid cache flushing. Here, you can also make pages cacheable forcibly for selected pages or all pages and decide whether to use the same cache for new visitors. The same tab contains a section where you can specify your username and password for HTTP authentication.

FPC hole punch is the section where you can configure specific blocks that will not be cached. For each hole punch, you should specify a path to the template containing the block, block class, CMS block ID or Widget code (for custom blocks), and store view.

In the Debug section, you decide whether to show the cache status of pages on the frontend and for which IP addresses. Besides, you enable/disable logging of warmer requests, as well as tags and backtrace for cache flushes.

Below, you can check how the Cron syntax looks:
