I would say that using more memory to achieve the same thing would be a
reasonable definition of "using memory less efficiently". It depends on
your application, for example IIRC squid uses about 40% more memory on
large caches under amd64 because of the huge linked-lists it uses for
indexing.
At 4GB it's not a cut and dried choice even if there are no
64-bit compatibility problems.
