In this article, we'll explain the Performance Settings available for you when activating a IONOS CDN or CDN Plus package.
Rather than selecting each of the settings manually, you can apply one of the following preset profiles:
- The Basic profile offers you the benefits of a global content delivery network (CDN). On average a website will load twice as fast. This is the safest profile that is least likely to interfere with any page resources.
- In addition to the CDN benefits, the Advanced profile offers basic web content optimization. This profile is appropriate for websites that want more performance than a basic CDN but may have issues with the full optimization.
- The Expert profile is recommended for WordPress. In addition to the CDN and basic optimizations, you get full web content optimization for a better website performance. This profile is appropriate for websites that want a faster performance.
|Caching Level||Use the caching level to determine how much content on your website is to be cached. • Basic: Resources accessed using a query string are not cached. • Advanced: Resources accessed using a query string are cached, but the query string is ignored. • Maximum: Resources are cached separately based on their query string.|
|Minimum TTL||Define how long the content of your website should be cached on your visitors' computers.|
|Purge Cache||Use this option to clear the content currently stored on the CDN servers if you want to make changes to your website immediately available to your visitors.|
|Purge Single File||Rather than clearing the entire cache stored on CDN servers, you can enter the full URL to a single file you want to be deleted from the CDN.|
|Mirage™(Intelligent Image Loading)||All images on the website are rendered to the size of the visitor's device and do not load unless they are actually viewed.|
|Polish™ Image Compression (for CDN Plus Packages only)||Compress your images automatically for faster loading times.|
|Railgun™ (only in IONOS Performance and Managed Server packages)||In addition to static content, this option enables fast loading of dynamic web content.|
