Joerg Hoh updated SLING-12244:
------------------------------
    Description: 
In the context of Sling Models I found that a lot of calls to 
ResourceResolver.getParentResourceType(Resource) are done, which result in 
repository access. But this can happen also outside of it.

In a simple example (AEM wknd page) I found in total 320 calls to in total 36 
resources. Caching these can save around 280 requests to the repository, which 
a reduction in the range of 2-3% when it comes to repository access when 
rendering the complete page.
