My experience was similar, though the comparison was far from
rigorous. Given the better support for 32-bit applications, I
would suggest staying with a 32-bit system, unless one needs
to do serious number crunching.

That is to be expected, as your variables are now larger, e.g.,
a default int in C is now 64 bits, instead of 32. What you gain
is speed, and the space addressable in your programs.
