10 practical ways to achieve Magento speed optimization: Unleash your store’s true potential


Magento speed optimization can be a major boost for eCommerce revenue. Shoppers have high expectations for online stores, thus a slow e-commerce website can quickly turn them away. However, the question of how to make speed improvements keeps many store owners from optimizing their sites correctly. So, what are some ways to achieve Magento 2 speed optimization, and how can this decision deliver a better user experience? Read more to discover the importance of speed.

I. Why should you focus on Magento speed optimization?

In the dynamic realm of e-commerce, where competition is fierce and customer expectations are ever-rising, website optimization stands as a cornerstone of success. While the technical aspects of speed enhancement are undoubtedly crucial, it is essential to delve into the compelling reasons why such endeavors are worthwhile. Here, we unravel the multifaceted the most important reasons for optimizing your e-commerce website. 

  • The initial five seconds of your website’s loading time play a crucial role in determining conversion rates.
  • The conversion rate decreased by 4.42% with each added second of loading time between 0-5 seconds, and the highest one occurred for pages with 0-2 seconds of loading times. This means that a website that takes 5 seconds to load will have a lower rate conversion rate of 22.1% than a website that takes 1 second to load.

  • Nearly 70% of consumers state that a website’s page speed affects their willingness to purchase from an e-commerce website.
  • Google’s algorithm heavily weights page speed, thus the quicker your pages load, the more likely it is that you will appear higher in search engine results.

II. How to speed up a website: 10 practical ways to achieve Magento speed optimization

To optimize the speed of your e-commerce website without investing time and effort, avail of Magento speed optimization service and enhance the shopping experience of customers. Applying the 10 strategies below, your business can overcome these challenges and ensure your Magento 2 store delivers an optimal shopping experience for your customers.

1. Keep Magento updated

Ensuring Magento 2 is always up to date is a key approach to achieving speed improvements. Magento updates include performance enhancements, patches, and other necessary features and resources to keep it functioning properly and to avoid poor loading times caused by out-of-date systems. Keep up with the latest versions to make sure you’re using the most recent update of the platform and keep customers happy with their site experience.

2. Set up a content delivery network

 A content delivery network (CDN) places multiple server nodes in various geographic locations, improving scalability, offloading bandwidth due to large files, reaching a global audience efficiently, mitigating DDoS attacks, and enhancing reliability. In addition, it makes the website more attractive to customers and encourages them to stay longer. However, unlike your site’s cache, a CDN needs to be configured manually since it’s not automatically integrated into Magento.

Step 1: Access Configuration Settings

  1. Navigate to Admin > Stores > Settings > Configuration in your Magento dashboard.

Step 2: Configure Base URLs

  1. Select General > Web on the Configuration page.
  2. Open the Base URLs section.
  3. Enter the URL of your CDN’s static view files in the Base URL for Static View Files field.
  4. Enter the URL of your CDN’s JavaScript files in the Base URL for User Media Files field.

Step 3: Configure Base URLs (Secure)

  1. Open the Base URL (Secure) section.
  2. Enter the URL of your CDN’s static view files in the Secure Base URL for Static View Files field.
  3. Enter the URL of your CDN’s JavaScript files in the Secure Base URL for User Media Files field.

Step 4: Save Configuration

Click the Save button to apply the CDN configuration changes.

3. Use full-page cache and enable Varnish cache

Varnish Cache functions as an intermediary between web clients and web servers, effectively operating as a caching HTTP reverse proxy. Rather than directing every content request directly to the web server, Varnish assumes this responsibility, enhancing overall performance by alleviating the burden on the web server.

Activating Varnish and full-page cache is another way to make your Magento 2 website load faster. With a full-page cache, you may dramatically reduce loading times by creating cached versions of your site’s pages for users instead of executing separate queries for every request from users. As a result, your website responds to identical user requests with the same HTML, saving you time and effort by avoiding the need for additional queries or back-end processing.

However, Varnish works better than files when it comes to handling the process of enabling a full-page cache for your website. A web program called Varnish Cache can reduce the amount of network bandwidth used by your site and its overall response time. The following procedures can be used to enable Varnish Cache after installation: Stores > Configuration > Advanced > System > Full Page Cache > Caching Application > Varnish Caching

4. Optimize images

For photos on your website, use compressed images and file formats such as JPG, which will help to reduce file size and provide speed improvement in page load times.

Instead of depending on CSS resizing, get your image’s source file downsized to the ideal size. Striking a balance between image quality and size is crucial for e-commerce websites. High-quality images effectively showcase products, while smaller file sizes ensure faster page loading times and a seamless user experience. Achieving this balance requires a strategic approach that considers both technical and aesthetic aspects. Also, it is vital to use the correct file type – items should be in PNG, JPEG, or GIF format, and your site’s logo should be in PNG or SVG. Below are the differences among these image files. 

PNG: A lossless compression format that preserves high image quality, able to result in larger file sizes   

JPEG: A lossy compression format that results in smaller file sizes, good for photographs and images with complex details and color variations, introducing artifacts, especially at high compression levels   

GIF: A lossless format that supports animation, good for small, simple animations and icons, limited color palette   

SVG: An XML-based vector graphic format that is scalable to any size without losing quality, more complex to create and edit than raster formats

5. Re-Index products

Products that are not properly indexed will not appear correctly and may cause your website to slow down. Re-indexing these products will consolidate scattered data into a single database, improving the overall performance of your e-commerce store.

This is a relatively simple process. You can begin re-indexing in Magento Admin by following these steps:  

  1. Access Index Management:
  • Log in to your Magento Admin panel.
  1. Navigate to System > Index Management:
  • From the top menu bar, select “System.”
  1. Select Product Indexes:
  • In the left-hand panel, locate and click on “Index Management.”
  1. Choose Product Indexes for Re-indexing:
  • In the “Index Management” section, identify the product indexes that require re-indexing. Typically, you’ll need to re-index the “Catalog Product Flat” and “Catalog Product Category Flat” indexes.
  1. Initiate Re-indexing Process:
  • Select the checkboxes next to the indexes you want to re-index.
  1. Choose Re-indexing Mode:
  • From the “Action” dropdown list, choose “Reindex.”
  1. Confirm Re-indexing:
  • Click on the “Submit” button to initiate the re-indexing process.

6. Eliminate unused data

The Magento Datalog collects critical information about your products, but it still retains unnecessary data, which might slow down the loading time of your e-commerce website. For example, you may have data accumulated, such as details on products you no longer sell, but which occupy disk space. It is vital to delete this data in order to keep your pages loaded quickly and maintain consumer happiness.

In a few simple actions, you can clear up your Magento Datalog and experience noticeable speed improvements. Select System > Configuration > Advanced > System from the Admin Panel. Expand the MySQL Message Queue Cleanup option and configure the various properties. Once you’ve entered all of the necessary information and are ready to go, save the settings.

7. Select a hosting provider

E-commerce websites, particularly those built on Magento, demand robust hosting solutions to ensure optimal performance and responsiveness. To prevent sluggish loading time and disappointing user experiences, Magento websites require a hosting provider that can accommodate their unique resource demands. Two prominent hosting providers that cater to these needs of Magento websites are Amazon Web Services (AWS) and Nexcess.  These platforms offer a range of features and capabilities tailored to Magento’s specific requirements, ensuring seamless operation and scalability.

8. Reduce JavaScript and CSS

Firstly, it is crucial to understand how these languages impact page rendering and identify optimization opportunities.

JavaScript, on the one hand, enhances web page interactivity and dynamic behavior. However, overuse or poor optimization can significantly slow page loading speed. This includes time-consuming parsing and execution of JavaScript code, which requires HTTP requests from the server, and manipulation of the Document Object Model (DOM), which can cause additional processing and delays in page rendering.

CSS, or Cascading Style Sheets, on the other hand, is responsible for visualizing web pages. Poorly optimized CSS can affect page loading time by increasing parsing and styling time, requiring HTTP requests for each CSS file, and adding redundant or unused CSS rules, which can slow down page rendering and increase the overall page loading time.

The technique to improve Magento speed optimization is to combine your JavaScript and CSS scripts into a single file rather than numerous separate files using the following steps:

  • Go to the Admin Panel and then Stores > Configuration > Advanced.
  • Select Developer from the advanced menu.
  • Find the JavaScript settings option and select the Merge JavaScript Files, Minify JavaScript Files, and Enable JavaScript Bundling options to “Yes.”
  • Change the value of the Merge CSS Files and Minify CSS Files options under CSS preferences to “Yes.”

9. Set your indexers to “Update on Schedule”

When it comes to scheduling their indexers, Magento users have two choices: Update on Save or Update on Schedule.

Updating on save means that every time you save a change to a product, category, or attribute, the related indexers will run and update the indexes. This can be resource-intensive and slow down your website, especially if you are making a lot of changes.

Updating on schedule allows indexers will only run at the scheduled time when your website traffic is typically low. This is a more efficient way to update your indexes and will help your e-commerce website run faster.

In general, it is recommended that you set your Magento indexers to update on schedule during periods of low website traffic, typically during late-night hours or weekends. This will help to improve the performance of your website and ensure that your indexes are always up-to-date.
