2. $wgParserCacheType *
Cache for the result of
rendering a page. Rendering the wikitext is very
intensive, thus it should be cached.
3. $wgMessageCacheType * // found no documentation
It refers to the interface messages. They are used all the time. It's a
good idea to cache them.
== Question 2 ==
What are the benefits and draw backs with using either of the two
options below, after excluding the other options?
* CACHE_DB
* CACHE_ACCEL - (eAccelerator in my case)
CACHE_DB uses the database, and thus performs worse than a specific
cache accelerator. It may also produce db deadlocks.
CACHE_ACCEL seems a good solution for your case. If you had several
servers, they would have independent caches, that's why memcached is
preferred, but since it's on a single box, seems ok.
