In this article, we'll explain the Performance Settings available for you when activating a IONOS CDN or CDN Plus package.
Profiles
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.
Performance Settings
| Setting | Explanation |
|---|---|
| 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. |
| Auto Minify | Choose which content of your website (JavaScript, CSS, HTML) should be "minified" (optimized) to reduce script size and improve page loading speeds. |
| Rocket Loader™ | Use the Rocket Loader to load JavaScripts of your website asynchronously. |
| 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. |
