Although I agree the ORM layer really accelerates how quickly you can get
benefit out of memcached, it is certainly incorrect that mod_perl is
required to get any benefit.  The initial testing has already shown modest
benefit.

As another example, you have a fully parsed MARC::Record object
representation for a given biblio.  You can store that object away, and the
next time you need to reference it (when a user clicks for the details page,
or the MARC page, etc.) you can retrieve and use it without having to call:

   - biblioitems for the marcxml
   - MARC::Record->new_from_xml

That example may not be something we do in practice (better targets abound),
but you can see conceptually where the benefit can kick in w/o mod_perl.  In
particular, if you have a lot of Apache front-ends, you can use a
consolidated cache server and get the benefit across all (one copy of the
object available to all of them).

At the end of the day, I think we are very close to seeing real
production-scenario benefit from memcached, and still somewhat far from
using mod_perl.  In large part that is because mod_perl requires broad
changes to the codebase before the first benefit is returned whereas
memcached can slip in optionally now.
