The Perfmatters plugin was created with simplicity in mind.
The main way this plugin helps speed up your site is by disabling things that might not be used on your site. For example, by default emojis load on every single page of your site. If you don’t use them, this is simply slowing it down. By disabling it, the script no longer loads and so it reduces your overall number of HTTP requests and your page size.
Another great optimization is to limit your post revisions. These can quickly fill up your database and slow down your site. By limiting them you can ensure a fast and snappy database.
This plugin isn’t designed to replace your caching plugins or image compression plugins, but rather work alongside them to further strip out things that aren’t needed on your WordPress site.
Perfmatters is compatible with all popular optimization plugins like WP Rocket, Cache Enabler, Autoptimize, etc.
