Haven't "lurked" on the list for a while, so apologies if I'm asking the
answered, however:
Bearing in mind the non-goals of the paper,
i.e.
Finding a precise database size at which the 64-bit version becomes
more advantageous than the 32-bit version.
Finding a precise amount of RAM to optimize caching the database.
Any prescriptive guidance on these bearing in mind that most of our DIT's
contain more than just user info? Also, how do multiple processors affect 64
bit DC performance?
What about DC specific settings in 64bit environments, do these change at
all, since larger cache configurations are assumed - the thinking is here
that you wouldn't bother with 64 bit dc's without the extra memory.

although nothing official, we've done testing HP internally and were quite
comfortable using a single well-sized 64-bit DC (well-sized meaning our
whole DIT cached in memory) serving one of our sites with approx. 4 Exchange
Mbx. servers (I believe all dual-proc) with a total of 20.000 mailboxes. It
worked like a charm.
