Introduction to Magento 2 Performance Optimization

Magento 2 is built to serve thousands of users at once. However, without proper speed optimization, Magento stores can become slow and frustrating to use. Slow Magento stores can negatively impact conversion rates and SEO rankings. Magento performance speed optimization is a comprehensive approach and often requires multiple fixes. This guide provides actionable tips and recommendations for Magento 2 performance optimization. The goal of this guide is to improve Time to First Byte (server response time), Google PageSpeed and Core Web Vitals scores. Optimizing Magento performance can lead to improved customer satisfaction.

Why Magento 2 Speed Optimization Matters

Magento 2 requires a lot of web server resources to run smoothly. A slow Magento store frustrates customers and leads to higher bounce rates and lost sales. Research shows that a one second delay in loading speed time can reduce conversions by up to 7% (Mageplaza). So optimizing Magento 2 speed is essential to maintain customer satisfaction and stay competitive in e-commerce landscape.

Optimizing Magento 2 Configuration

Optimizing Magento 2 configuration is crucial for website performance. One of the key configuration is to enable full page caching which can significantly improve Magento 2 site performance. Full page caching stores HTML responses to skip back-end processing and database queries. To enable full page caching run the command:

Also, Redis can be configured for default caching. Redis is an in-memory data store that can handle 60,000+ connections and 50,000+ queries per second. Follow the installation process for your setup. These will reduce load times and overall website performance.

1. Enable Varnish Cache for Full-Page Caching

Varnish cache is a powerful HTTP accelerator recommended for Magento 2 full-page caching. It stores static content in memory and serves it to users without hitting the backend. Configuring Varnish cache in your Magento admin will reduce page load times and server load.

Besides Varnish, Magento 2 has a default cache that can be enabled if turned off. This default cache can be configured to work with Redis with specific command-line instructions to optimize performance and data retrieval speed compared to other in-memory data stores.

Example: By enabling Varnish cache, one Magento store reduced its average page load time from 4.5 seconds to under 2 seconds, huge improvement in customer retention.

2. Implement Redis for Default Caching and Session Storage

Redis improves Magento 2 speed and performance by managing default caching and session storage efficiently. Unlike disk-based caching, Redis stores cache data in memory which speeds up page rendering and reduces database load. Check out the resources for all the details on how to configure Redis in Magento.

Example: With Redis default caching, one Magento 2 store was able to handle more traffic without performance degradation.

3. Optimize Product Images

Large unoptimized images can slow down your Magento website. Make sure images are optimized by using techniques like image compression and modern formats like WebP to reduce file size. Also enable lazy loading images to defer loading of offscreen images until user scrolls to them.

Example: Compressing images and enabling lazy loading speed reduced page size by 40%, page load time and Google PageSpeed Insights score.

4. Minify CSS and JavaScript Files

Minification removes unnecessary characters and whitespace from CSS and JavaScript files reducing their size and page load time. Techniques like minify CSS files and minify JavaScript files can be enabled via Magento’s built-in tools or third-party extensions. Advanced JS bundling further optimizes static resources by grouping JavaScript files efficiently.

5. Switch to an Optimal PHP Version

Magento 2 supports multiple PHP versions. Running your store on the latest stable PHP version (PHP 8.x) will improve performance and security. PHP 8 is much faster than older versions.

However having multiple PHP versions installed can cause component dependency conflicts especially when upgrading to the current Magento version. Make sure to check package prerequisites for a smooth upgrade.

Example: Migrating from PHP 7.4 to PHP 8.1 improved backend processing speed by 20%.

6. Update to the Latest Magento Version

Magento releases updates with performance improvements and Magento security patches. Keeping your version up to date will give you the latest speed optimization and bug fixes. In Magento 2.4.x and above versions, Elasticsearch is enabled by default with default settings which will improve search and simplify the configuration.

7. Use a Content Delivery Network (CDN)

A CDN distributes your static files across global servers reducing latency and speeding up content delivery to users worldwide. Integrating a CDN with your Magento site will improve website speed and reliability especially for international customers. Using optimized images with a CDN will further improve load times and overall site performance.

8. Optimize Your Store Theme

Your Magento theme affects performance. Avoid heavy themes with too many third party modules. code structure optimization to render faster and reduce overhead.

Upgrading to the latest Magento version and using features like Varnish Cache will improve response times and overall Magento website functionality.

9. Enable Magento’s Production Mode

Magento’s production mode is faster than developer mode as it serves pre-compiled and JavaScript and CSS files and disables debugging. Switch to production mode for live stores to get the best speed and reduce page load times. Production mode also generates static view files in advance which are then served from the cache for better performance optimization.

Command to enable production mode:

Verify the mode in the admin panel and ensure all static content is pre-generated.

10. Avoid Using Flat Catalogs in Magento 2.1.x and Above

Although flat catalogs (both ‘flat catalog category’ and ‘flat catalog product’) improved product and category loading, Magento now discourages their use as they can cause performance degradation. Rely on Magento’s default indexing and caching mechanism instead.

11. Clear Database Logs Regularly

Your Magento store’s database logs can slow it down. Clearing logs regularly will improve database performance and reduce load times. Use the Magento admin panel or command line to clear logs. Magento also generates and updates flat tables during the indexing process to improve performance by simplifying data retrieval and reducing the impact of slower queries on multiple tables.

12. Utilize HTTP/2 Protocol

HTTP/2 allows multiple requests over a single connection, so static files like CSS, JS and images load faster. Make sure your web server supports HTTP/2 to get faster website load speed times.

To further speed up loading times you can enable GZIP compression on an Apache server by updating the .htaccess file. Add the necessary configuration to enable the mod_deflate module which compresses static resources for faster network transfer.

13. Conduct Regular Website Performance Audits

Do a website audit for your Magento 2 store using tools like Google PageSpeed Insights, GTmetrix or Pingdom. Analyze website speed performance and find bottlenecks. Use those insights to implement ongoing speed optimization techniques.

Database and Search Optimization

Database and search optimization are key to Magento 2 performance optimization. Using Elasticsearch can improve search results and performance. Elasticsearch is a solution for Magento 2 speed optimization and search accuracy. Install Elasticsearch according to your setup. After installing Elasticsearch turn it on in Magento 2 Admin Panel. Also optimizing database queries and indexing can improve performance. Clearing database logs and optimizing search are good Magento 2 performance optimization techniques.

Hosting and Infrastructure Optimization

Hosting and infrastructure optimization play a significant role in Magento 2 performance optimization. Choosing a reliable hosting provider that meets Magento’s minimum system requirements is essential. A good hosting provider should have a high-speed backend cache, such as Redis or Memcached. Additionally, using a content delivery network (CDN) can improve page loading times by reducing the distance between the user and the server. Cloudways offers a managed Magento hosting solution that meets all Magento 2 system requirements. These optimizations ensure that your Magento store runs smoothly and efficiently, providing a better user experience.
