With over 1,000 plugins tagged as cache at the WordPress plugin directory, it has become widely optional for site owners to easily progress the speed of their site pages. This is how caching works with WordPress: Caching generates a copy of your web page and stores it on your server as static files, say as HTML documents or cached database queries. Then after, when a visitor reaches a particular page of the site, the server shows off a cached page rather than re-querying your database and generating it dynamically. This process speeds up the page response time and reduces the server resources needed for creating and serving a web page.

The simplest and quickest way to implement a caching system on a website or webpage is by using WordPress plugins WordPress cache plugins are available in various types that serve individual purposes. There are specialized plugins that cache the whole HTML pages, plugins that cache all SQL queries and data objects, plugins which minimize Javascript and CSS files and even more server side solutions. Prior to seeing some of the top WordPress cache plugins, there are few tips which you got to be aware of in order to best use caching methodology.

Caching Tips & Techniques for WordPress:

Although you use definite plugins, making use of caching methods for database and objects that subjects to a good development process is quite vital. WordPress comes with excellent options to to easily implement varying degrees of data caching. There are two different caching methods accompanied by WordPress. Non Persistent and Persistent. The non-persistent type of data remains in the cache while the page is loading. Persistent kind of data depends on the database to work and cached data can auto expire after sometime.

Based upon the SQL query, widgets that depend on both these caching methods can be easily created. Tow widgets created out of these two approaches will essentially make the same output by making use of different methods for data retrieval and results caching. Below mentioned are few tips that help in speeding up WordPress site with caching.

1. MySQL Query Cache

As WordPress uses MySQL and almost all page load results in MySQL queries for logins, it is quite proven that this data didn’t change since the past request. In order to change the MySQL configuration file, you would possibly accomplish the root access which would not be available on shared hosts.

2. PHP Compiler Cache

WodPress also has a PHP application that allows calling from the web server to the PHP interpreter. This program reads the script files and compiles them into opcode which can be executed easily. However, this process could consume some time based upon the size of your script. APC and eAccelerator are few of the well known PHP compiler caches.

3. WordPress Internal Caching

If you are using a slow database server, it is indeed a great idea to store frequently used data in a serialized form on disk. WordPress also has an integrated disk-cache that stores barely changing data such as categories and users in a special folder.

4. Static Pages

If you are not able to apply all the other caching methods or if they are not enough to handle with, there is only one absolute solution to go with. It is nothing but caching the entire generated pages. This can be done by means of an amazing plugin named WP Cache. This plugin will cache the entire generated page on the disk and skip the complete WordPress execution on upcoming requests. The cache will be generated and cleared once again after a particular time or when you publish a new post. Though this method is extremely fast, it will eventually break some functionality like plugins which add dynamic content to your blog.

5. Additional Tips to rely on

Consider using the latest or current WordPress version. Updating to the latest available version of WordPress lets you to avail on the newest features, security fixes and performance optimizations.
