Implementing Content Delivery embedded caching
Content Delivery embedded caching speeds up your website by storing commonly used or resource-intensive objects in a cache on the server. The cache keeps these objects available rather than making a database round trip to reinitialize them every time they are requested. By default, Content Delivery embedded caching is enabled for all types of data, but you can configure exactly what is and isn't cached (which includes the possibility of caching nothing at all).
