CDN Edge Caching and WordPress Server Caching plugins are two different approaches to improving the performance of a website.
CDN Edge Caching refers to the use of a Content Delivery Network (CDN) to cache the content of a website at various locations around the world. By caching content at the edge of the network, near the end-user, the CDN can quickly serve the content to the user without having to make a round-trip back to the origin server. This can significantly improve the loading speed of a website, especially for users located far from the origin server.
WordPress Server Caching plugins, on the other hand, are plugins that are installed on a WordPress server and cache the content of a website directly on the server. These plugins can be used to cache various elements of a website, such as images, HTML, and database queries. By caching these elements on the server, the plugin can serve the content directly from the cache, which can reduce the load on the server and improve the overall performance of the website.
Both CDN Edge Caching and WordPress Server Caching plugins can be useful for improving the performance of a website, but they serve different purposes and have different benefits. CDN Edge Caching is generally better for improving the loading speed of a website for users located far from the origin server, while WordPress Server Caching plugins are better for reducing the load on the server and improving the overall performance of the website. Ultimately, the best approach for you will depend on your specific needs and the performance requirements of your website. It’s possible to use both CDN Edge Caching and WordPress Server Caching plugins together for even better performance, but it’s important to carefully consider the trade-offs and potential compatibility issues before implementing both.
