A reasonable question might be "do you expect installations to need this data to grow?" If so and the growth is enough it might well be ARCHITECTURALLY better to move to 64 bit at some point.

And it might be different on different machines. So if 64-bit runs better in your current machine, don't through away your old AR code, because it might be useful in your DR site or a new machine. My advise is to benchmark because I found myself more than once with the wrong assumption. If you choose to benchmark, try to keep your benchmark as close as possible to the real workload ... Toy systems behave different than real ones.
