What swap ultimately comes down to though is you, the user. If you foresee needing more than 32 gb ram, feel free to add more swap space. If you don't, maybe 8 gb or so just to be on the safe side. If you really need 32 gb swap space, I'd recommend just getting more ram, as that will be much, much faster than thrashing.
