Hi, {{first_name|friend}}. 👋
Welcome to Issue #186 of Loop WP!
Last week was about prepping your WooCommerce store's hosting for the long holiday season.
This week is about two of my favourite plugins for boosting WooCommerce performance.
Let’s go! 👇
Checkout Summit 2026
Checkout Summit is the independent WooCommerce conference where developers, agencies, and product builders gather to share insights, innovations, and strategies.
Attend, and you won’t leave without ideas, connections, and tactics that can earn back your investment, fast.
WooCommerce Performance isn’t just about Hosting
💡 WooCommerce performance is never just about hosting, but as we discussed last week, it’s where good foundations are laid.
Plugins can make a measurable difference, especially in stores with heavier themes, page builders, or many third-party extensions.
Two of the most popular optimisation plugins are Perfmatters and WP Rocket.
I use both Kinsta and Rocket.net for hosting WooCommerce sites.
Kinsta recommends WP Rocket in their setup, and so does Rocket[dot]net, which even offers a free license for each site.
Using WP Rocket and Perfmatters Together for WooCommerce
Most people treat WP Rocket and Perfmatters as competitors.
🧠 In reality, good performing WooCommerce stores often use both…not because they overlap, but because they solve completely different problems:
WP Rocket gives you fast, cached pages.
Perfmatters gives you cleaner, lighter pages.
(The above is an oversimplification, but you get the idea.)
They complement each other when configured correctly, and the combination is often stronger than either tool on its own. That’s exactly how I use them for my clients.
WP Rocket
WP Rocket’s strength is its all-in-one approach. It handles caching, preloading, basic asset optimisation and database cleanup.
For WooCommerce stores without server-level caching, this is incredibly valuable. **
What WP Rocket is best at:
Full-page caching for shop, product and content pages.
Automatic exclusion of cart, checkout and account pages.
File optimisation that works well for most themes.
Database and lazy loading improvements.
🚀 This gives you the performance foundation: fast pages, reduced server load and consistent response times.
** (Although you will have to turn off Preloading with some hosts due to PHP threads [e.g. Kinsta], and CPU resources on shared hosts. WP Rocket page caching is also turned off by default with Kinsta.)
Perfmatters
Perfmatters works at a different level than WP Rocket.
Instead of caching entire pages, it controls what loads on each page. This complements WP Rocket by reducing unnecessary assets before caching even takes place.
What Perfmatters is best at:
Script Manager: disabling CSS and JavaScript on pages where they are not needed. **
WooCommerce-specific tweaks (removing fragments, password meter, etc., when safe).
Lightweight performance features that don’t interfere with caching.
** (This is my favourite feature of Perfmatters, but the new code snippets feature has me excited!)
Final Thoughts
Both tools share some features, but they are not competitors.
WP Rocket makes pages fast after they’re built.
Perfmatters makes those pages smaller, lighter and quicker to process.
🚨 You will have a choice about which plugin to use for those specific features, and some to be aware of:
Lazy Load.
Remove Unused CSS + Script Manager used aggressively together.
Combining CSS/JS in WP Rocket when Perfmatters is doing granular control.
✅ You can safely use both plugins side-by-side if configured correctly.
Licensing/pricing (and not honouring legacy customers)
How they enabled “by default” the new automatic payment feature for Add-ons
But overall, I am still happy to recommend WP Rocket, and Perfmatters can have my money, “no questions asked.” 🤣
I am a legacy user of WP Rocket, so recent changes have caused me a little bit of concern for the future:
There are lots of performance plugins out there, like NitroPack or FlyingPress (which get good user feedback), so do some research, but it’s hard to go wrong with Perfmatters and WP Rocket. ❤️
Quick Note
Last week, I was going to share Karol Król’s video 10k+ WordPress Plugins Analyzed Through PCP and PHP_CodeSniffer, as WooCommerce came out terribly.
Something didn’t seem right (and it’s not Karol’s fault). I reached out to James Kemp (WooCommerce Core Product Manager)and showed him Karol’s original LinkedIn post, where James noted something very important: things aren’t as bad as they seem.
“Some context on the WooCommerce score: PluginScore uses WordPress.org's default coding standards rather than WooCommerce's own ruleset (https://github.com/woocommerce/woocommerce/blob/trunk/phpcs.xml) , so things like namespaced classes get flagged as "unprefixed globals" when they're actually fine, for example.
That said, there are some older PHPCS annotations in the codebase that could use a refresh. Good prompt to take another look!“
That’s it for this week, {{first_name|friend}}. 👋
