What I meant was what was the impact on running 32 bit binaries on the
64 bit OS (e.g. run your benchmarks there as well).
Unless I've completely missed something (always a possiblity), 32-bit
code runs *exactly* the same when the CPU is in 64-bit mode. In the
benchmarks posted, the Athlon64 (and possibly the P4; I'd have to
check later) was actually running in 64-bit mode at the time, even
though the binaries were 32-bit.
