It's actually ENABLING DeltaRPM support (as the latest DNF update now does) 
that makes assumption 2. DeltaRPMs reduce download bandwidth consumption at 
the expense of a lot of CPU power. It's a tradeoff between 1. and 2. If you 
have 1. more than 2. (as is the case for me), then DeltaRPMs actually make 
your updates slower. If you have 2. more than 1., they make your updates 
faster.
