A Beginner's Guide to Installing and Using the ​Perfmatters WP Plugin

Introduction

WordPress, a popular content management system (CMS), offers numerous plugins to enhance website functionality, user experience, and performance. One such plugin is Perfmatters. It streamlines your website by removing unnecessary features, optimizing code, and implementing a variety of performance-enhancing tweaks. This guide will provide you a detailed step-by-step installation process and show you how to harness Perfmatters to its full potential.

Installing Perfmatters on Your WordPress Site

Purchase and Download the Plugin: Before the installation, you need to purchase Perfmatters from their official website. After successful purchase, you can download the plugin in a ZIP file format.

Upload the Plugin to WordPress: Log in to your WordPress admin dashboard. Navigate to the "Plugins" section on the left-hand sidebar, and click on "Add New". On the top of the next page, you'll find the "Upload Plugin" button. Click on it, and you'll see the option to upload the ZIP file that you just downloaded.

Install and Activate the Plugin: After uploading the ZIP file, click on "Install Now". WordPress will unpack the plugin and install it for you. Once the installation is complete, click on "Activate Plugin". You can find the Perfmatters plugin in your installed plugins list.

Understanding and Using Perfmatters' Features

Script Manager

One of Perfmatters' most powerful features is the Script Manager, which lets you disable scripts on a per-page/post basis. This means you can prevent unnecessary scripts from loading on specific pages/posts, improving load times. 
To use this feature:

Navigate to any post or page in your WordPress admin dashboard.

Click on "Script Manager" in the top admin bar.

You will see a list of all scripts and styles loading on that page/post.

You can disable any script or style by clicking on the "Disable" button.

Performance-Basic Settings

Perfmatters allows you to disable unnecessary WordPress default options that could be slowing your site down. To tweak these settings:
Go to "Settings" > "Perfmatters" in your WordPress admin dashboard.

Here, you will see a list of options under different tabs like "Options", "Extras", "Tools", etc.

Under the "Options" tab, disable features like emojis, embeds, XML-RPC, jQuery migrate, etc. Most of these features are not required for a basic website, and disabling them can improve performance.


For a beginner, it is recommended to keep the default settings in Perfmatters. However, once you are more comfortable with the plugin and have a better understanding of your website's needs, you can experiment with different settings to see what works best for you.

DNS Prefetching

This feature allows you to specify domains for the browser to perform DNS lookups in the background while the user browses. This can reduce latency when the user clicks a link. To enable DNS prefetching:

Navigate to the Perfmatters settings page (go to "Settings" > "Perfmatters").

In the "Extras" tab, you'll find the "Add DNS Prefetch" section. Here, add the URLs you wish to prefetch.

Preloading

Preloading can help prioritize specific resources to ensure they load faster, enhancing user experience. 
To enable preloading:
Navigate to the Perfmatters settings page.

In the "Extras" tab, find the "Add Preload" section. Here, add the URLs you want to prioritize.

Disable RSS Feed

If your website doesn't require an RSS feed, you can choose to disable it. This can help reduce unnecessary requests. To disable the RSS Feed:
Navigate to "Settings" > "Perfmatters" in your WordPress dashboard.

In the "Options" tab, you'll find the "Disable RSS Feed" option. Simply enable this to disable the RSS feed.

Remove jQuery Migrate

jQuery Migrate is a script that helps developers move from older versions of jQuery to newer ones. Most modern WordPress sites do not need this, and removing it can reduce load times. To remove jQuery Migrate:
Navigate to "Settings" > "Perfmatters".

Under the "Options" tab, find the "Remove jQuery Migrate" option and enable it.
