GPL Premium Plugin
Perfmatters is a very lightweight WordPress performance plugin. The main focus of this plugin is to reduce your page size and number of HTTP requests. It allows you to disable many unneeded features like emojis, XML-RPC, RSD Link, Shortlinks, RSS Feeds, and lots of other things to speed up your site. It’s not a caching plugin, but it provides those features that a caching plugin doesn’t offer. Perfmatters doesn’t conflict with any other cache plugin. You can use both Perfmatters and any other cache plugin combination together for better loading speed. The actual size of the Perfmatters plugin is also very less between 150KB – 160KB. So, this plugin isn’t going to impact your site performance as other big size plugins do.
