since I originally pointed out these costs, I would like to add that you
guys are doing an extraordinary job in reducing them to the max.
especially the improvements in the latest stable release were amazing.
I'm looking forward to the next set of improvements ;-)

the object instantiation costs can't be avoided, and I think that if
you've done your optimizing homework (which DBIc has largely done), you
end up with the limits of your programming language. so in that sense, a
comparison of ORMs in different languages (as requested by the OP) would
be interesting. my personal experience is that Java (with Hibernate as
the ORM) performs better there, but this is just my feeling and not
actual benchmark results.
