If a 64-bit processor could run two 32-bit programs at the same time, or if
a 64-bit binary ran two equivalent 32-bit processes simultaneously, then it
would make sense that it could be twice as fast. But, that's only true if
it takes the same amount of time to perform a 64-bit operation as a 32-bit
operation (which isn't the case).
