Perfmatters Review: Is It The Right Plugin For You?

A performance plugin can be a magic wand that solves all your website speed issues. Poor user experience? Dismal PageSpeed scores? These plugins can fix a lot of the problems you have.  

In my research, I found that WordPress administrators recommend Perfmatters a lot. It’s popular for its granular control and lightweight design. It works differently by focusing on removing unnecessary code and features to make your site fundamentally faster.

But, is that enough? In this article, we’ll break down exactly what Perfmatters does, who it’s for, and whether it’s the right investment for your WordPress site. 

TL;DR: Perfmatters is a powerful plugin but it works best in tandem with other plugins. For a more comprehensive performance solution, try Airlift.

What features were we looking for in Perfmatters?

To set the stage, we built a messy test site on purpose: heavy page builder, multiple forms, sliders, social sharing, analytics, and eCommerce add‑ons. Dozens of plugins, lots of requests, slow load times, and poor Core Web Vitals—the kind of real‑world bloat many WordPress sites struggle with.

We installed Perfmatters to see how much of that bloat we could remove without breaking functionality. Here’s exactly what we looked for:

Caching

WordPress caching can be powerful but Perfmatters is not a caching plugin. A good caching plugin is fantastic for improving your server’s response time (TTFB) by delivering a pre-built page. Unfortunately, Perfmatters doesn’t do any of it. 

🗒️ Expert Advice: WP Super Cache and Perfmatters combined could be a better solution. 

Image Optimization

When it comes to image optimization, Perfmatters focuses exclusively on how your media loads, not on the image files themselves. It provides excellent lazy loading for images, iframes, and videos, which defers off-screen media and dramatically improves initial load times. It also helps you tackle Core Web Vitals directly by allowing you to preload critical images to improve your Largest Contentful Paint (LCP) and add missing image dimensions to prevent Cumulative Layout Shift (CLS). 

What Perfmatters does not do is file optimization, such as image compression or conversion to modern formats like WebP. Compressing images reduces their file size, which is a fundamental part of making any page fast.

🗒️ Expert Advice: Plugins like WP Rocket and Airlift are a more comprehensive image optimization solution. 

Asset Optimization

Asset optimization is undoubtedly the core strength of Perfmatters and the primary reason most users choose it. It gives you surgical control to selectively disable CSS and JavaScript files on a per-page or even sitewide basis. For example, if your contact form plugin loads its scripts on every single page of your site, you can use the Script Manager to ensure it only loads on your “Contact Us” page. This single action can eliminate unnecessary code and speed up your entire site.

Beyond this, Perfmatters offers advanced features like the ability to Remove Unused CSS, which is critical for fixing render-blocking warnings, and robust controls to defer or delay JavaScript until user interaction. This granular control over what loads and when is what sets Perfmatters apart from many all-in-one solutions, allowing you to meticulously remove bloat that slows down your pages.

🗒️ Expert Advice: Take a WordPress backup. This can help you recover your site if the asset optimizations accidentally crash it. 

Database Optimization

Cleaning your database and optimizing it can help prevent lots of WordPress errors. Over time, your database gets cluttered with unnecessary data. Perfmatters allows you to easily clean up this bloat, including old post revisions, auto-drafts, trashed items, spam comments, and expired transients. You can also schedule automatic cleanups on a daily, weekly, or monthly basis. This lets you “set it and forget it,” ensuring your database remains optimized without any manual intervention. 

Pricing

Perfmatters pricing varies depending on the number of websites you use. It is a premium plugin with no free version. The standard pricing structure is as follows:

It’s important to note that your purchase includes not just the plugin itself, but also one full year of plugin updates and premium support.

What Perfmatters is Missing Compared to All-in-One Solutions

While Perfmatters is a master of granular control, its specialized focus means it intentionally leaves out several key features. Understanding these downfalls can be integral to your decision. 

The Better Alternative – Airlift

Airlift offers a fundamentally different approach that can be ideal for users looking for a single solution. It acts like a dedicated performance expert that continuously works on your site. It analyzes each page individually to build and maintain a custom optimization strategy, adapting daily to any changes you make. Here’s a breakdown of what this intelligent automation actually does:

Final Thoughts

The biggest flaw of Perfmatters is that it’s an incomplete toolkit. It forces you to juggle multiple plugins for caching and image optimization. 

This is why you should use Airlift instead.

Airlift is a fully automated, all-in-one solution that replaces your entire performance stack. It handles everything—caching, image optimization, CDN, and asset control—without the complexity or risk.
