How can you improve site speed using Sitecore?

Utilizing a Content Delivery Network (CDN) is a highly effective method for improving site speed in Sitecore and web applications in general. A CDN consists of a distributed network of servers strategically placed in various geographic locations. When users access your site, the CDN serves cached content from the nearest server to them, significantly reducing latency and improving load times.

This method enhances the user experience by decreasing the time it takes for pages to load, as the distance between the user and the server is minimized. Additionally, CDNs often optimize delivery of static content like images, stylesheets, and scripts, further contributing to increased speed.

In contrast, using local font files instead of web fonts may have some positive impact on performance but does not provide the comprehensive speed improvement that a CDN offers. Disabling all third-party plugins may reduce functionality without necessarily enhancing speed, as it removes potentially beneficial features. Serving content only to logged-in users limits accessibility and does not directly relate to improving site speed for all users.
