Speedy Caching

WebSpheres web page caching features are also better than WebLogics: They were easy to enable and administer and didnt require any page code changes, as WebLogics tag-library-based page caching design required.

WebSphere can also integrate with the Apache Web servers built-in cache (Apache is WebSpheres default Web server), and IBM sells a separate HTTP load balancer, WebSphere Edge Server, as another performance-enhancing option for Web farms.

We found WebSpheres built-in caching features plenty fast. For example, we tested them with a database catalog page of an online bookstore we wrote in Java and saw average page generation times drop from 184 ms with caching turned off (the default) to 12 ms with caching turned on—a fifteenfold improvement.

WebSphere doesnt match the breadth of caching features that Oracle Corp.s Oracle9i Application Server provides (it caches HTML and database content), but it still stands out as a sophisticated player in this space.
