Porting 32 bit C++ code to 64 bit - is it worth it? Why?

Question

I am aware of some the obvious gains of the x64 architecture (higher addressable RAM addresses, etc)... but:

• What if my program has no real need to run in nati

Answer 1

It's pretty unlikely that you'd see any benefit unless you're in need of extreme security measures or obscene amounts of RAM.

Basically, you'd most likely know intuitively if your code was a good candidate for 64-bit porting.
