8 quick wins to optimise your Magento store’s performance

The quick wins that make Magento faster

Speeding up your Magento store doesn’t always require huge development projects. In fact, many of the most effective improvements come from smaller, targeted changes, the kind that tidy up hidden clutter, reduce unnecessary weight and help Magento run more smoothly behind the scenes.

Below are some of the quickest wins you can implement:

1. Audit and trim unnecessary Magento modules

Magento’s modular setup is incredibly flexible, but that same flexibility makes it easy for your site to accumulate extensions you no longer use. It’s surprisingly common for stores to have dormant or outdated modules still running quietly in the background.

Disabling or removing them can instantly reduce load times, cut down unnecessary processing and lighten the front-end code your customers have to download.

Each extension typically comes with its own scripts, stylesheets and functionality. Even when the feature seems small, the performance footprint can be much larger than expected. Auditing your installed modules helps you pinpoint what’s actually contributing to slowdowns and what’s simply taking up space.

As store admins often install far more than they consistently use (whether for one-off campaigns, testing ideas or features that never fully launched), a cleanup can be one of the quickest, easiest performance wins available.

2. Compress and optimise your images

Images are often the biggest contributor to slow page loads, so optimising them is one of the quickest ways to speed up a Magento store. Switching heavy JPEG or PNG files to WebP can dramatically reduce file sizes without affecting visual quality, instantly making pages feel lighter and faster.

Additionally, large hero banners are uploaded at 2000–3000px wide, even though the displayed version only needs a much smaller size. Resizing and compressing these alone can have a noticeable impact on performance.

As your catalogue evolves, so does your collection of product images and video assets. Magento’s media storage can become cluttered with outdated or unused files, which adds unnecessary weight behind the scenes. Tidying this up keeps things organised and ensures you're only serving the images that matter.

Because images, especially hero banners, have an effect on your Largest Contentful Paint (LCP) score, improving them benefits both user experience and SEO. A cleaner, optimised image setup results in faster loads, smoother browsing and a more responsive store overall.

3. Clean up your JavaScript and CSS payload

JavaScript and CSS are essential to how your Magento store looks and behaves, but they can also be a major source of slow rendering, delayed interactivity and overall sluggishness when they’re not kept in check.

Over time, it’s common to accumulate layers of scripts and styles as new features are added, old ones are replaced and experiments come and go, which increases the amount of code the browser has to download and process.

A good starting point is removing dead or unused code. Many stores still carry old scripts, abandoned libraries or functionality left over from previous builds. These files often load on every page, even if they’re doing absolutely nothing. Cleaning them out reduces your payload and lightens the workload for the browser.

Beyond deletion, it’s also worth reviewing how your remaining JS and CSS are delivered. Consolidating compatible files, deferring non-essential scripts and minimising render-blocking assets can have a noticeable impact on how quickly on-page key elements appear and respond.

Streamlining your codebase doesn’t require major redevelopment, just careful auditing and trimming. But the results can be significant, eg. faster load times, smoother interactions and a front end that feels far more refined.

4. Avoid multiple versions of jQuery

Multiple versions of code happen more often than you’d think - different extensions or custom modules loading their own jQuery versions or additional libraries. This leads to duplication, inconsistent behaviour and unnecessary weight on every page.

Consolidating everything to a single version improves your website's stability and cuts down the amount of JavaScript the browser needs to process.

Similarly, reducing inline CSS wherever possible can make a noticeable difference. Inline styles add bulk directly to your HTML and limit the browser’s ability to cache and optimise assets. Moving these styles into well-structured stylesheets creates cleaner markup, faster-rendering pages and a more maintainable codebase overall.

Magento developers can often unlock substantial speed gains simply by tidying scripts and styles, removing redundancy and tightening up delivery. It’s a high-impact improvement that rarely requires major rework - just thoughtful optimisation and attention to detail.

5. Enable and configure full-page caching properly

Full-page caching is one of the most powerful performance features Magento provides, but it only delivers its full benefit when it’s configured correctly. Many merchants assume that simply switching it on is enough, yet an unoptimised cache can leave a huge amount of speed on the table.

In reality, FPC needs thoughtful setup. Cache warmers and sensible TTL (time-to-live) settings influence how effectively your pages are served. When these pieces aren’t aligned, Magento ends up regenerating more content than necessary, and this can reduce the speed gains you should be seeing.

It’s also important to understand the difference between Magento’s built-in caching and using Varnish. The built-in cache is functional, but Varnish is dramatically faster and far more efficient at handling high-traffic environments. If your store is still relying on the default option, you could be missing out on a major performance lift.

And don't overlook a CDN. Cloudflare, for example, is a genuinely quick win, serving static assets from edge locations closer to your visitors and reducing the load on your origin server at the same time. For many stores, it's one of the easiest performance improvements you can make.

6. Review your hosting environment

Your hosting environment has a bigger impact on Magento’s performance than many merchants realise. Even a perfectly optimised site can feel slow if the underlying infrastructure isn’t up to the job.

Magento relies heavily on CPU power, sufficient RAM, fast SSD storage and an up-to-date PHP version to run efficiently. When any of these are underpowered or outdated, they create bottlenecks that slow down response times and increase server load.

Because Magento handles complex catalogues, dynamic content and resource-heavy operations, it genuinely needs a robust hosting stack behind it. A cheap or generic hosting package may look appealing on paper, but it simply won’t provide the performance headroom Magento requires - especially as your store grows.

Something as simple as upgrading hardware or moving to a newer PHP version can deliver immediate, measurable speed improvements. Need faster, more reliable hosting for your Magento store? Take a look at our Magento hosting plans.

7. Reduce 3rd-party scripts and tag clutter

External scripts on a Magento website are one of the most common (and most underestimated) causes of slow page load times. While each one may seem harmless on its own, they can collectively add seconds, not milliseconds, to how long a page takes to become usable.

Marketing and analytics tools – like chat widgets, review platforms, tracking pixels, heatmaps, A/B testing tools and similar resources – all introduce extra network requests, large script bundles and delayed execution. Over time, as more and more of these are added for campaigns or experiments, the performance impact becomes significant.

Regularly reviewing and trimming these scripts can make a dramatic difference. Many stores have old tags running that no longer serve a purpose, duplicate tracking from previous agencies or tools that were trialled and forgotten. Removing what you don’t need instantly reduces overhead and speeds up rendering.

Even consolidating (not just removing) third-party scripts is one of the simplest ways to create a noticeably faster, more responsive customer experience without touching your core Magento build.

8. Audit GTM, remove old pixels, use server-side tracking

Google Tag Manager containers often become a dumping ground for years’ worth of old marketing tags, test pixels and tracking snippets that are no longer needed. Each of these loads on your pages (whether you’re using them or not), which quietly slows things down in the background.

Regularly auditing your GTM container – removing redundant tags, consolidating duplicate tracking and disabling anything that’s no longer part of your marketing stack – can make a noticeable difference to performance.

There’s also a growing advantage in shifting certain types of tracking to server-side tagging. By moving heavier scripts off the browser and onto the server, you can reduce the amount of JavaScript that needs to run on the customer’s device. This not only cuts load times but also improves data accuracy.

Cleaning up Google Tag Manager and streamlining your tracking setup is a relatively small task that can deliver outsized performance gains. Over time, Magento stores tend to accumulate layers of legacy tags, from agency changes, marketing experiments, seasonal campaigns and tools that were trialled and abandoned.

Ongoing Magento support to keep your store performing well

A well-optimised Magento store doesn’t stay that way forever.
