For the type of use of the OP (databases, etc.) i don't know, but
for scientific computations we observe a massive performance advantage
running in 64 bits mode (by this i mean more than 20%, i have seen some
Maple formal computations run 100% faster). The only problem with
64 bits mode is that some ports may have problems, but, as far as i
know, these ports are more desktop oriented than server oriented. For a
server i don't see a reason to run in 32 bits mode. Contrary to
some frequent assertions the increase in size of binaries is
extremely limited as can easily be checked. This is very largely
compensated by the increase in the number of registers. The possibility
of using more than 4 gigs memory is just one advantage of 64 bits mode,
and by the way, very few of our machines have more than 4 gigs memory,
and they don't lack it at all.
