On the flip side, it does make sense that the point where 64-bit builds become better memory-wise than 32-bit builds could be substantially below 4GB of RAM, given that 32-bit builds can run out of memory due to fragmentation of the address space. Where the tradeoff lies is probably best determined by experiment. (There are also presumably some security improvements with 64-bit.) -David -- 𝄞 L.
