Assume for a moment that I have a menu with ~1000 items in it (I know, from an IA point of view it's not ideal, but some clients do 'require' it). I haven't actually tested this yet, so I'm only thinking through based on what I've seen happen on other systems... but generally, this takes a lot of time to put together.
Is there a way to specify in a .ss template that the output of a certain region should be cached as rendered for a period of time?
I'd love to hear more (or be pointed to a source to read more) about the partial caching in 2.4. We've faced similar problems and thus far solved them by using limited caching of objects (DataObjectSet, etc.) using Zend_Cache. It's worked ok, but I agree that it be helpful to have more options, such as caching part of a template, and would be happy to help that come to fruition. I see that Zend_Cache is now included in the 2.4 branch too so that's good news.
