Why would such a small, simple program need to be 64 bit? Exactly what changes when moving puTTY from 32 bit to 64 bit? It now takes up more memory?

- rb12345 10y agoThe most likely reason is ASLR support, since you have more address space available for randomisation. Other than that, you can probably get a slight boost in performance from the differences between x64 and x86, but lose out if the code is particularly pointer-heavy.
- gfody 10y agoWe are well beyond moving to 64bit on a needs-only basis. At this point it's about dropping legacy and future proofing. There's also no reason 64bit apps should have a larger memory footprint; the ISA and addressing modes are actually much tidier.
