correct.
A 32-bit application can not go above 3GB in best case, often much less
due to dynamic linking, threads etc eating significant parts of the
address space. 2.5 GB or even less is more realistic to expect.
Well, there is also some experimental 32-bit OS:es getting close to the
theoretical 4GB limit per process (2^32 == 4GB), but only at significant
performance penalty and added internal complexity.
A 64-bit application (which also requires 64-bit CPU and 64-bit OS to
run) on the other hand is practically unlimited in size, only limited by
how much memory you can stuff into the box.
