Best Cache Plugin for WordPress blog and Website

What is Caching?

Excessive load times can harm your website in more ways than one way. There are quite a few ways to improve your site’s speed but caching has the greatest impact on your site.

Data of a web page is cached in order to reduce load times of website. Whenever you return back to a frequently accessed website, its higher chances that your browser will have a good portion of the site page files are stored within its cache. That means the browser needs to receive less ‘fresh’ information from the site, resulting in a faster load time of that website.

As Cache Plugins work by saving the dynamically generated HTML files and serving them from the cache (i.e. reusing previously generated data) whenever a request is made, rather than loading all of the PHP scripts from WordPress every time you hit refresh.

There are different ways to make your website faster: specialized plugins to cache entire rendered HTML pages, plugins to cache all SQL queries and data objects, plugins to minimize JavaScript and CSS files and even some server-side solutions.
But even if you use such cache plugins, using internal caching methods for objects and database results is a good development practice, so that your plugin doesn’t depend on which cache plugins the end user has. Your plugin needs to be fast on its own, not depending on other plugins to do the dirty work. And if you think you need to write your own cache handling code, you are wrong. WordPress comes with everything you need to quickly implement varying degrees of data caching. Just identify the parts of your code to benefit from optimization, and choose a type of caching.

WordPress implements two different caching methods: Non-persistent and Persistent.

In Non-Persistent caching the data remains in the cache during the loading of the page. WordPress uses this to cache most database query results.

Persistent Caching depends on the database to work, and cached data can auto-expire after some time. WordPress uses this to cache RSS feeds, update checks, etc.

Non-Persistent Cache Link
When you use PHP WordPress functions such as get_posts() or get_post_meta(), WordPress first checks to see whether the data you require is cached. If it is, then you will get data from the cache; if not, then a database query is run to get the data. Once the data is retrieved, it is also cached. A non-persistent cache is recommended for database results that might be reused during the creation of a page.

The code for WordPress’ internal non-persistent cache is located in the cache.php file in the wp-includes directory, and it is handled by the WP_Object_Cache class.

We need to use two basic functions: wp_cache_set() and wp_cache_get(), along with the additional functions wp_cache_add(), wp_cache_replace(), wp_cache_flush() and wp_cache_delete().

Cached storage is organized into groups, and each entry needs its own unique key. To avoid mixing with WordPress’ default data, using your own unique group names is best.


How to Choose Best Cache Plugin for Your WordPress Website

The first step is to identify that what is your requirement from your caching plugin and create criteria accordingly. Criteria could include: CostComplexity and intuitiveness, Power and functionality & Support.

Some plugins come with extra features such as integration with content delivery networks and minification means removing all unnecessary characters from source code. These all features enable your site to run even faster but are really only necessary for large sites.

Here are list of WordPress Best Cache Plugin as Below:

WP Super Cache

WP Super Cache is  among the fast caching engine for WordPress that produces static html files.

WP Super Cache plugin generates static html files from your dynamic WordPress blog. After a html file is generated your web server will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

The static html files will be served to the vast majority of your users, but because a user’s details are displayed in the comment form after they leave a comment those requests are handled by the legacy caching engine. Static files are served to:

  • Users who are not logged in.
  • Users who have not left a comment on your blog.
  • Or users who have not viewed a password protected post.

Most of your visitors will be served static html files. Those users who don’t see the static files will still benefit because they will see different cached files that aren’t quite as efficient but still better than not cached. This plugin will help your server cope with a front page appearance on or other social networking site.

Garbage collection is the act of cleaning up cache files that are out of date and stale. There’s no correct value for the expiry time but a good starting point is 1800 seconds if you’re not using legacy mode. If you are using that mode start with an expiry time of 600 seconds.

Recommended Settings for WP Super Cache
