Folks,
FWIW, the applications where I did direct 32 / 64 comparison were
a) several data warehouse tests, with databases > 100GB
b) computation-heavy applications (such as a complex calendaring app)
And, as others have pointed out, I wasn't comparing generics; I was comparing
Athalon/Xeon to Opteron. So it's quite possible that the improvements had
nothing to do with going 64-bit and were because of other architecture
improvements.
In which case, why was 64-bit such a big deal?
