0.00 avg. rating (0% score) - 0 votes


Performance and scalability are crucial factors for any ecommerce platform, and Magento 2 has made significant strides in these areas compared to its predecessor, Magento 1. In this article, we will examine the key differences between Magento 1 and Magento 2 in terms of performance, focusing on faster page load times, enhanced indexing, advanced caching mechanisms, scalability improvements, and optimized code base.

Faster Page Load Times

Magento 2 offers faster page load times compared to Magento 1, thanks to several improvements, including:

  • Reduced JavaScript Size: Magento 2 utilizes RequireJS to better manage and minimize the size of JavaScript files, thus reducing the page load time.
  • Image Compression: Magento 2 supports image compression out-of-the-box, decreasing the size of images and improving overall page load time.
  • Full Page Caching: Magento 2 includes full page caching, which stores the full HTML output of a page, significantly reducing the time needed to load a page.

Enhanced Indexing

Indexing is a process that transforms store data to improve the performance of your store’s storefront. Magento 2 has introduced several enhancements to its indexing system:

  • Update on Schedule: Magento 2 uses a more efficient indexation process called «Update on Schedule.» This feature only updates the index when required, rather than on every page load, resulting in faster storefront performance.
  • Asynchronous Indexing: Magento 2 supports asynchronous indexing, which enables partial index updates, reducing the time required to re-index data.

Advanced Caching Mechanisms

Caching is essential for improving the performance of an ecommerce platform. Magento 2 has introduced various advanced caching mechanisms:

  • Varnish Cache: Magento 2 has native support for Varnish Cache, a powerful HTTP accelerator that caches content and serves it faster to users.
  • Redis Cache: Magento 2 supports Redis Cache as a backend cache solution, improving performance by storing frequently accessed data in memory.
  • Browser Caching: Magento 2 includes better browser caching configuration, which allows the browser to cache static assets, reducing server load and improving performance.

Scalability Improvements

Magento 2 offers improved scalability, allowing online stores to handle more traffic and transactions with ease. Key scalability improvements in Magento 2 include:

  • Separate Database for Order Management: Magento 2 supports a separate database for order management, enabling better handling of high-order volumes and reducing the risk of performance bottlenecks.
  • Improved Database Performance: Magento 2 has optimized its database queries and schema, which results in better performance, especially during peak traffic times.
  • Multi-Source Inventory (MSI): Magento 2 includes native support for MSI, enabling merchants to manage inventory across multiple locations and improve the efficiency of their supply chain.

Optimized Code Base

Magento 2 has an optimized code base that contributes to better performance. Some of the key optimizations include:

  • Refactored Code: Magento 2 has refactored its core code to remove legacy components and streamline the codebase, resulting in better performance and easier customization.
  • Better Extension Conflict Management: Magento 2 uses a plugin system that reduces conflicts between extensions, minimizing the risk of performance issues due to incompatible extensions.
  • PHP 7 Support: Magento 2 supports PHP 7, which offers significant performance improvements over previous PHP versions.


The performance and scalability enhancements in Magento 2 make it a superior choice for ecommerce businesses when compared to Magento 1. Faster page load times, enhanced indexing, advanced caching
