Lazy loading

Using CDN

CDNs (Content Delivery Networks) are globally distributed networks of servers that bring content closer to the user. By using a CDN, you can reduce the distance between the server and the user, which in turn reduces page load times.

Optimizing CSS and JS formatting

Optimizing CSS and JS formatting involves reducing file size by removing spaces, comments and empty lines. This can help improve your site's performance by reducing page load times.

Best practices for maintaining high performance

Regular performance monitoring

To maintain good performance, it's important to regularly monitor your site's performance using tools such as Google Pagespeed Insights, Google Lighthouse, WebPageTest, Pingdom Tools, GTMetrix and YSlow. This will enable you to spot performance problems as soon as they occur and take the necessary steps to resolve them.

Perform tests before and after modifications

Before making any changes to your site, it's important to run tests to assess current performance. Once changes have been made, you should run tests again to check whether performance has improved. This allows you to measure the impact of the changes and adjust your approach if necessary.

Regularly update plugins and frameworks
