I think you're missing a major point here.  While
executing code written for V5 in V6 might be a
reasonable starting place for speed comparisons, it
is not reasonable to compare the results without
considering possible improvements that could be made
to the V6 code.

In Graphics, for example, wrapping a large number of
Points or Lines in a single head is an important step
to get V6 Graphics to render efficiently.  This was not
an option in V5 since it was unimportant for the V5

Clearly these are things that are worth discussing and
in fact there are some slowdowns.  I'm pretty confident
that Wolfram is working on them, as they've already
released V6.0.1.
