Input on caching methods?

Thanks.

I think I probably don't want to go the "cache the whole page" route since CI doesn't have enough knowledge about when or how the page changes. There are also some user-specific elements to the page and I don't want users that aren't logged in to have access to admin controls :-)

Having said that though, I think as a first step I'll work on adding some stats so I can see more clearly the site usage patterns. It might be that most of the users are non-members in which case there's probably a gross level of caching that would help in most cases. I can get more finer-grained caching once I know better where the need is.
