Dynamic Caching

As described previously, static caching is a valuable benefit, increasingly so with the amount and size of static elements in an application. However, with the current trend toward more personalized, portalized, and dynamic sites, dynamic caching is much more useful. In addition to the reasons cited previously, dynamic requests tend to use far more enterprise resources in order to build a response. Dynamic content often requires the most resource-intensive work in an enterprise system, so dynamic caching can dramatically enhance performance. Revisit Figure 19-1 at the beginning of this chapter and consider the amount of computing power required at each tier to build these requests. CPU utilization, memory, and connections are ...
