Speeding Up WordPress Themes with Caching Techniques
Posted on 16th June 2023
When it comes to WordPress development, one of the most important factors to consider is performance. A slow website can result in lost visitors and potential customers, which is why it’s important to ensure that your site is as fast as possible. One way to speed up WordPress is to use caching techniques.
Caching is a way of storing data in memory so that it can be accessed more quickly. By caching data, you can reduce the number of requests that need to be made to the server, which can speed up your website. There are a number of caching plugins available for WordPress, but in this article, we’ll be focusing on two of the most popular: W3 Total Cache and WP Super Cache.
W3 Total Cache
W3 Total Cache is a powerful caching plugin that is used on millions of websites. It is available as a free and premium version. The free version includes all the features you need to get started, but the premium version includes additional features such as CDN support and more.
To install W3 Total Cache, head to the plugin page and click “Install Now”. Once the plugin is installed and activated, you’ll need to head to the settings page and configure the plugin.
The first thing you need to do is select the type of caching you want to use. There are four options:
- Disk: This is the most basic type of caching and is suitable for most websites. It stores the cached data on the server’s hard drive.
- Memcached: This is a more advanced caching method that uses memory to store the cached data. It is faster than disk caching but can be more expensive to set up.
- Redis: This is another advanced caching method that uses memory to store the cached data. It is even faster than Memcached but can be more expensive to set up.
- APC: This is the fastest type of caching but is only available on certain servers. If your server doesn’t support APC, you won’t be able to use this caching method.
Once you’ve selected the type of caching you want to use, you can then enable the caching options you want to use. There are a number of options available, but we recommend enabling the following:
- Browser Cache: This caching method stores static files in the browser’s cache. This means that the browser will load the cached files instead of requesting them from the server, which can speed up your website.
- Page Cache: This caching method stores the rendered HTML of pages in the cache. This means that the server doesn’t need to generate the HTML for each page request, which can speed up your website.
- Object Cache: This caching method stores data such as database queries in the cache. This means that the server doesn’t need to run the same database queries each time a page is requested, which can speed up your website.
Once you’ve enabled the caching options you want to use, you can then configure the settings for each option. We recommend leaving the default settings as they are, but you can experiment with different settings to see what works best for your website.
WP Super Cache
WP Super Cache is another popular caching plugin that is used on millions of websites. It is available as a free and premium version. The free version includes all the features you need to get started, but the premium version includes additional features such as CDN support and more.
To install WP Super Cache, head to the plugin page and click “Install Now”. Once the plugin is installed and activated, you’ll need to head to the settings page and configure the plugin.
The first thing you need to do is select the type of caching you want to use. There are three options:
- Simple: This is the most basic type of caching and is suitable for most websites. It stores the cached data on the server’s hard drive.
- Mod_Rewrite: This is a more advanced caching method that uses memory to store the cached data. It is faster than disk caching but can be more expensive to set up.
- PHP: This is the fastest type of caching but is only available on certain servers. If your server doesn’t support PHP, you won’t be able to use this caching method.
Once you’ve selected the type of caching you want to use, you can then enable the caching options you want to use. There are a number of options available, but we recommend enabling the following:
- Browser Cache: This caching method stores static files in the browser’s cache. This means that the browser will load the cached files instead of requesting them from the server, which can speed up your website.
- Page Cache: This caching method stores the rendered HTML of pages in the cache. This means that the server doesn’t need to generate the HTML for each page request, which can speed up your website.
- Object Cache: This caching method stores data such as database queries in the cache. This means that the server doesn’t need to run the same database queries each time a page is requested, which can speed up your website.
Once you’ve enabled the caching options you want to use, you can then configure the settings for each option. We recommend leaving the default settings as they are, but you can experiment with different settings to see what works best for your website.
