Comment (by jmorliaguet):

 considering javascript resources, there is a simple optimization that can
 be done:

 for a given site, go through all portlets, gather the javascript resources
 into a single file and place them in a global "per site" cache. The cache
 needs to be invalidated when a portlet is modified / added / removed.

 Note that some existing sites might break (in cases where the javascript
 code is dependent on the actual HTML content of the page, this can
 happen), so this ought to be implemented as a new option for instance in
 the theme's tool  (for example: [x] use a global file for javascript
 resources).

 that's a "pull" model since you collect all resources from existing
 portlets. The advantage is that it is easy to implement, it only requires
 small modifications from the existing code, the drawback is that it can
 lead to a large javascript file, but thanks to the server-side cache and
 the browser cache / gzip possibilities it really doesn't matter.

 the other model is to push resources into the <head> of the page, it is
 the way I would implement it today, as long as the result of the
 concatenation of all the resources can be easily cached per key (that's
 the case in nxthemes where resources are per theme/page/perspective/mode).

 for CSS the issue is different since portlets do not declare CSS resources
