Magento Full Page Cache Extension reduces your site's latency, increases your Web server request rate, reduces database load, and will make your site much more responsive feeling for your customers. When a store comes to the Internet, content is critical. However, slow and inconsistent performance of a website will diminish the value of even the richest content; therefore, it is a tremendous pressure on infrastructure cutting down the amount of processing and delivering the content to customer without any time lag or delay.
Magento Full Page Cache allows all elements and aspects of the site being stored in the cache so that the content will be displayed promptly. When an user visiting a webpage for the first time, Magento generates and delivers a page to the visitors and automatically save a copy of it to the cache. Each subsequent time when the user request arrives, the system does not request Magento to generate a page, but returning the copy of the page from cache.This greatly reduces database and server load. An extension significantly increases the load speed of your Magento store.
