There are several ways to improve the speed of a PrestaShop website, here are a few common methods:
Optimize images: Large images can slow down your website, so it’s important to optimize them by reducing their file size. You can use image optimization tools to compress images without losing quality.
Use a Content Delivery Network (CDN): A CDN can help to distribute the load on your server by caching your website’s content on servers located in different regions. This can improve page load times for visitors located far away from your server.
Use caching: Caching can help to speed up your website by storing commonly used data in memory, reducing the need to dynamically generate content on each page load. PrestaShop has built-in caching options, but you can also use caching plugins or modules.
Minimize HTTP requests: Every time a page loads, the browser makes HTTP requests for different elements on the page (CSS, JavaScript, images, etc.). Minimizing these requests can help to speed up your website. You can use tools like Chrome DevTools to identify and reduce the number of HTTP requests your website makes.
Optimize database: Keeping your database clean and optimized can also help to improve the speed of your website. You can use the built-in database optimization feature in PrestaShop or use a module to optimize your database regularly.
Use a performance-optimized hosting: Using a hosting provider that is optimized for PrestaShop can help to speed up your website. This can be done by using VPS or Dedicated hosting.
Upgrade to the latest version: Keeping your PrestaShop up to date can also help to improve the speed of your website as new versions usually come with performance improvements.
Note: It’s important to test the speed of your website before and after making any changes to see the impact of the optimization.
