I don't believe this has anything to do with JSF 2.0 features. Woodstock
combines CSS, JavaScript, and images to avoid generating multiple
requests. At one time, requests were generated for separate component
resources, but performance suffered greatly. Although the requests were
small, the number of requests have far more impact on performance than
the size of the request. (This is particularly true for images)
Although, this is relative to how many components are used in the page.
If the browser's cache is enabled, these resources should only be loaded
once.
If you are interested in the performance improvements made to Woodstock
4.2, please see the thread below. This includes combined files, lazy
loading, gzip compression, etc.

Also take a look at the Woodstock head tag for performance related
attributes. For example, webuiAll and webuiJsfx can be used to tweak the
overall download size, depending on what features you need.
