That number was always weird and never made much sense. 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.
