I should have indicated in my earlier post that magazines which do
side-by-side hardware testing are saying that the AMD Athlon 64 is
indeed faster than the Pentium 4; for example look in the January issue
of Maximum PC magazine. they have a followup test supplementing an
earlier review of Athlon vs. Pentium systems. Their testing results
speak better than my faltering around with words. Tom's Hardware Guide
has also compared Socket 939 Athlon systems to the latest that Intel
has; I can't remember THG's exact judgement but it was overall more
favorable to the Athlon systems.

You should see an increase automatically due to more registers being
available (assuming the compiler makes good use of them). Other than
that, I suspect the only increase you will see is in parts that use
"long long" or __int64.
Also keep in mind, compilers are very new to 64bit compiling - it will
take a while for them to optimize to the full potential.

As for SQLite, it is unlikely that you will see any performance
difference between a 32 bit or 64 bit compile of SQLite unless you are
specifically working with working sets that are larger than 4GB -- that
is, working sets that would not fit in a 32 bit process.
When compiled to run as a 64 bit process, any program will use more
memory simply because data alignments are typically on a wider boundary
and pointer sizes are that much larger.
"64 bit computing" is one of the great myths of marketing foisted upon
the computing industry. Now that "ghz ghz ghz" seems to be largely
dead as a marketing myth, it would seem that "64 bits or die" is the
next great frontier.
There are real advantages to 64 bit, but "everything is just faster
with a recompile" is definitely not one of them.
