Perfmatters 2.6.8 – Lightweight WordPress Performance Optimization Plugin

Description

Caching plugins make pages load from memory; Perfmatters tackles what’s inside those pages. Most WordPress sites ship emoji scripts, embeds, dashicons, jQuery Migrate and a dozen plugin stylesheets to visitors who never use them. Perfmatters gives you a toggle for each, and a Script Manager to unload any asset per page, post type or URL pattern.

It is small (a few hundred KB), doesn’t add its own front-end weight, and pairs well with a page cache such as WP Rocket or your host’s server cache. Expect better Largest Contentful Paint and Total Blocking Time scores once delayed JavaScript and unused CSS removal are tuned.

Key features

• Script Manager to disable CSS/JS per page, post type or regex
• Delay JavaScript until user interaction
• Remove unused CSS generated per page
• Local hosting of Google Fonts and analytics
• Lazy loading for images, iframes and YouTube embeds with preview
• Preload, prefetch and preconnect hints plus database cleanup

Best for

• Site owners chasing Core Web Vitals scores
• Developers who want fine-grained control over what loads where
• WooCommerce stores stopping cart scripts from loading on blog pages

Requirements

• WordPress 5.0+ and PHP 7.4+
• Works alongside most caching plugins (disable overlapping options in one of them)

What you get

• The original, unmodified Perfmatters plugin files, version 2.6.8 (updated 11 September 2026)
• Released under the GPL licence
• Use it on as many sites as you own or build for clients
• Instant download from your Moryvanta account after checkout

Good to know

• Moryvanta is an independent GPL redistributor and is not affiliated with or endorsed by forgemedia (Perfmatters). Product names and trademarks belong to their owners.
• Good to know about licensing: the GPL covers the Perfmatters files and their updates, not the developer’s licence key. If you’re asked for a licence key or activation during installation (for instance to enable automatic updates), that licence is sold separately – contact Moryvanta support and we’ll help, offering a licence through Moryvanta where available or pointing you to the original developer.
• Automatic one-click updates from the vendor need an active key; all optimisation features run locally.
• Test “Delay JavaScript” and “Remove unused CSS” on a staging copy first – aggressive settings can break sliders or forms.
• Moryvanta support covers downloading and installing the files.
