Go to the Performance -> Page cache and page cache is the most important feature in the W3 Total Cache setup. When a visitor requests a page, the WordPress will create that page content and display it to you. When enabling the page cache, again when some other visitors or the same visitor requests that page, it will automatically display the page faster without loading to the server and querying the database. The importance of page cache is that it reduces the server load and loads the page much faster.

Opcode Cache

OpCode cache is for your PHP script. In a WordPress website, if a user makes a request, the PHP code has to read, parse, compile, execute and gives the output. But when you enable OpCode cache, the compiled PHP scripts are stored in the memory, so that it need not take the entire process to give the result. By enabling this, it saves a lot of time and displays the result quickly. But OpCode cache is available only in the premium version of W3 Total Cache.

Database cache

The database is a location where all your data related to your website is stored. Without a database, none of your websites will work. So the database is like a heart for any website. When a data is requested from the visitor, the query will fetch the database and display the information. But again and again, if the same data is fetched, it takes the same time for every load wasting the time. So by using database cache, this query fetching time is reduced and as soon as the same data is requested, it displays the result quickly. With the help of this cache, you can reduce the time to display the page, posts etc and improves the performance of your site. But when your website is running on a shared server, then enabling this database cache will reduce the performance. If you are using dedicated server or VPS, the enabling database will be much beneficial.  Please follow the Database cache in the general settings.

Object cache

The object cache is mainly used to save complex queries and store its result in memory. So instead of fetching the complex query every time, the result stored in the memory will display quickly and reduces your server loading time. But object cache lifetime is only for one request. If your website is running with a dedicated server or VPS, then object cache works well and increases your website performance whereas, if it’s on the shared server then it might slow down your website. Please follow the object cache in the general settings.

Browser Cache

Go to the Performance -> Browser Cache page and follow the settings by using the below screenshots. A website is a collection of files that intend to create web pages. In the website, there will be images, logo, JavaScript, CSS files etc. A browser cache is that it stores all these files locally in the user’s browser. That means if a user visits your websites first page, and if he moves to the second page, the time to load the second page will take much lesser time because all the static files such as images, logo are stored in the visitor’s browser by enabling browser cache. So that the user will get a good experience and speeds up your website loading time.

CDN stands for Content Delivery Network. CDN is generally a group of servers located all over the world.With the help of CDN, the page can be loaded fast.

Reverse Proxy

Reverse Proxy is usually between tour website visitor and your server. When a visitor requests a page in your website, the server actually displays the result by fetching the database.

By doing this, the loading time of a page is completely down. The most popular reverse proxies are Nginx and Varnish. But to be noted that the cache must be purged whenever there is a change in that page. Tick on the Enable checkbox and specify your IP address in order to enable reverse proxy.

  • Enable reverse proxy caching via varnish
