Why Is Magento 2 Slow?

Magento 2 performance can be pretty slow, which is frustrating to owners, developers, and users. This can be for several reasons, including:

  • Distant hosting location
  • Old hardware
  • Too many unused tools
  • Heavy designs

Let’s take an in-depth look at each of those and explore how to mitigate such issues.

Main Reasons for Slow Magento Website Speed and Performance

  • Hosting: If your website’s host is far away, your site might be slow. Using a closer host can help.
  • Hardware: Magento needs good hardware. For example, it should have at least 2GB of memory.
  • Data caching: Without this, websites can’t remember past user actions. This can slow down performance.
  • Catalogue: Some catalogues can make pages load faster, although not everyone agrees.
  • CSS and JS: If these are not combined, they take up more space and slow down the site.
  • Too much JavaScript: This creates large files that slow down the site.
  • Old version of Magento: Newer versions are faster and safer.
  • Many extensions: Too many tools or features can slow things down.
  • Unused tools: Remove tools you don’t use. It helps speed things up.
  • Debug log: These are files that remember errors. They can make a site slow if they get too big.
  • Too much Varnish cache: Sometimes, the built-in cleaner works better than Varnish.
  • No CDN: A CDN can make sites load faster.
  • Not using secure connections: Secure connections can load pages 15% faster.

Let’s address these issues and review how to speed up a Magento 2 website. But before that, you need to see if there’s actually a problem on your page.

How to Check Site Performance

How to Test Magento Performance

Owners of online stores, like those built on Magento 2, need to check their site’s speed regularly. Checking your store’s performance can help you spot any issues early. Without these checks, small problems can grow and start to damage the user experience.

By using tools to monitor Magento speed, you’re taking a proactive step to ensure your website stays on top form and offers the best experience for your users.

Tools to Monitor Magento 2 Speed

  1. Pingdom: A useful tool that measures your site’s speed from various locations worldwide. Enter your website link, pick a location, and the tool will provide performance results and helpful tips.
  2. GTmetrix: This service offers a speed performance score and gives suggestions for areas needing improvement.
  3. Webpagetest: This tool goes in depth, allowing various settings for testing. After running three tests, it provides detailed data on your Magento store performance.
  4. Google PageSpeed Insights: A tool that compares your website to Google’s standards. It’s great for understanding how mobile users see your site.

Optimizing Magento 2 for Better Performance

If, after testing, you discover your online store is slow, it’s time to review your setup. Here’s how to speed up a Magento 2 store using available built-in Magento functionality and third-party extensions.

1. Regular Magento Updates

Every three months, Magento releases a newer version that usually comes with enhanced features, bug resolutions, and speed boosts. Regularly updating to these newer versions can make a significant difference to your site’s overall performance. Not keeping it updated might lead to unwanted issues down the road.

2. Evaluate Your Hosting Choices

Magento demands specific technical requirements, including an SSL certificate and a minimum of 2GB of RAM. While starting with shared hosting might seem cost-effective, it’s often not the best for optimal Magento 2 speed.

Select a hosting provider that can cater to Magento’s needs and offer scalability options as your store grows.

3. Manage Extensions Wisely

Extensions enhance Magento’s functionality, but having too many can bog down your website. Periodically review and get rid of extensions that are no longer needed. Commands such as bin/magento module:status, bin/magento module:enable, and bin/magento module:disable can help you to manage them.

4. Theme Selection Matters

Themes loaded with widgets, sliders, and custom blocks might look appealing but can be a drag on your site’s speed. Always test a theme’s speed, preferably with tools like GooglePageSpeed, before committing to it. This will ensure you achieve aesthetics and performance.

5. Prune Unused Fonts

Fonts, though seemingly minor, can impact website loading speed. Sometimes, unused fonts might still load and slow down your website. Periodic cleaning of fonts you don’t use can lead to noticeable improvements in speed.

Check the <head> section of your site’s source code for font links. Remove any font links you don’t recognize or use. This can typically be done in your theme’s settings or by editing the page’s XML layout.

6. Optimal Image Practices

A webpage laden with images can be slow to load. Implementing “lazy loading” can be a game-changer for Magento 2 performance optimization. Instead of loading all images immediately, this technique loads them progressively as the user scrolls, improving the initial load time.

For implementing lazy loading, you can either use built-in theme functionalities or add extensions from the Magento Marketplace that offer this feature. Extensions like “Magezon Lazy Load” can be useful.

7. Adopt New Image Formats

The WebP format, introduced by Google, offers a way to reduce image sizes significantly without compromising quality. Although Magento doesn’t support WebP directly, extensions like Magento 2 WebP Images can facilitate this transition, making your site much faster.

Search the Magento Marketplace for extensions that enable WebP image support, like “Magento 2 WebP Images”. Install and configure as per the guidelines. Remember to back up your site before making significant changes.

8. Reconsider Flat Catalogues

Flat catalogues were once a way to achieve website speed optimization. However, they’ve been known to cause problems in versions after Magento 2.1. These simplified tables aimed to reduce the number of database queries needed to render a page.

However, for versions of Magento beyond 2.1, flat catalogs can present more challenges than benefits, sometimes leading to bugs and performance issues.

If you’re using a Magento version later than 2.1, you may want to consider other strategies, such as database optimization, Varnish Cache or Full-Page Cache, HTTP/2, and others. To learn more about those alternatives, keep reading.

9. Don’t Use Standard JS Bundling

JS bundling groups many JavaScript files together to make webpages load faster. But in Magento, this doesn’t always work well. When your website tries to open a page, it waits to get all the JS files, even if it doesn’t need them all. This can slow things down.

10. Explore Advanced JS Bundling

Although conventional JS bundling might fall short in Magento, there’s an alternative: advanced JS bundling. This method is more discerning, supplying only the specific JS modules required by a particular page.

Systematically categorize your JS modules based on page type (e.g. product pages) or functional purpose (e.g. checkout procedures).

11. Implement Deferred JS Loading

When JS scripts load prematurely, they can bog down your site. By deferring the loading of JavaScript, you can prioritize content rendering, giving users the perception of faster page loading.

How to improve website speed with better JS loading? Examine the scripts on your pages to differentiate between essential and non-essential ones. Use script attributes, such as defer, or plugins/extensions that help defer scripts in Magento. Monitor page loads to ensure critical functionalities aren’t affected.

12. Streamline with JS/CSS File Consolidation and Minimization

A common challenge that modern websites face is juggling multiple CSS and JS files. These can cumulatively affect load times.

Thankfully, Magento offers intuitive tools to address this, allowing users to merge and minimize these files. This approach not only streamlines the backend but also provides users with faster page responses.

13. Cache Activation for Improved Load Times

When a user accesses a page for the first time, the page content is loaded from the server. Simultaneously, Magento automatically caches this page content. When you access that page again, instead of regenerating its contents, the server uses the cached version.

This caching mechanism improves load times and ensures a consistent appearance.

However, during website modifications, developers or designers might deactivate the Magento cache to make their work easier. If they forget to reactivate it afterward, site performance can take a hit.

14. Prioritize Essential CSS Loading

While styling is crucial for a site’s visual appeal, you also need to optimize Magento performance. Magento offers an innovative solution, allowing users to strategically load essential CSS files before others. This method ensures critical content is displayed promptly, without compromising on aesthetics.

15. Activate Production Mode for Peak Performance

Within Magento’s versatile ecosystem, different modes cater to various needs. Of these, the ‘Production Mode’ is tailored for live websites, offering the most optimized performance settings. Ensuring this mode is active can make the difference between a sluggish site and a fast-loading one.

16. Enhance Global Reach with CDN

In today’s globalized marketplace, businesses must cater to global audiences. This introduces the challenge of delivering content swiftly across vast distances. Enter content delivery networks (CDNs). These networks optimize content delivery based on user location, ensuring rapid access irrespective of geographical boundaries.

17. HTTP/2: The Next-Gen Protocol

The evolution from HTTP/1 to HTTP/2 brings significant improvements in website load times. Unlike HTTP/1, which opens a new server connection for each static file, HTTP/2 can process these files concurrently.

This concurrent processing of multiple static files under a single connection results in websites loading and rendering more quickly. This improves Magento performance as there’s no lag due to establishing multiple connections.

18. Advance to Varnish Cache

This open-source accelerator is endorsed by Magento’s team. Even with Magento’s in-built full-page cache, Varnish takes things a notch higher.

Varnish enhances HTTP traffic, conserves bandwidth, and significantly cuts down server response times. It is versatile, caching static and dynamic content. When files are in high demand, Varnish caches them into RAM, ensuring swift loading during subsequent requests.

19. Use Indexers for Data Categorization

Streamlining data display, Magento’s design uses indexers to categorize vast merchant data like prices, catalogue details, stores, and user data into organized tables.

These indexers simplify the representation of product and category data on the frontend. This means no more continuous complex MySQL queries in Magento 2. They are auto-reindexed by the core system, so they’re set right.

If you spot product discrepancies or face site speed issues, you can always reindex through CLI or from the Magento admin panel.

Magento Speed Optimization Extensions

If you are wondering how to speed up Magento 2 without compromising design and functionality, extensions are a good place to start. They are easy to implement, come with ready functionality, and make an instant difference to your site load speed.
