The add-on "Full page cache" is an excellent solution that allows you to win customer’s loyalty from the first click. This add-on increases the speed of your online-store, which not only increases sales, but also improves the SEO-rating of your website. When the add-on " Full page cache " is enabled, the server does not need to access the database and various blocks of the site every time to generate the page, it does this once, after which the next visitors are given a cached page. Full caching of the site’s pages has an intelligent system for cleaning the pages' cache when updating the product (also when buying goods), which clears the cache of the pages on which the product was displayed. You can also set the time of the actuality of the generated cache.
The response time of the server if the add-on "Full page cache" is not available depends on the fullness of the online-store, when the add-on is enabled the fullness of the store does not matter. Below are the diagrams "Response time" and "Longest transaction" with the add-on turned on and off while visiting the online-store with 25, 50 and 100 buyers at the same time:
When you clear the cache from the admin panel - the full cache of the pages will also be cleared!
Do not forget that full page caching requires more memory on your hard drive!
With new add-on's version 2.3 the cache is saved as compressed files, which saves space on hard disk in 8 times!
Also there is an opportunity to clean up expired files!
