Where is the proof that SSL even rates as a blip? I wonder because

Exactly.

There is the asymmetric crypto, but it does not happen in bulk, on the
client side its cost is dwarfed by the network costs, there is session
resumption (if the web site enables it), and most web sites are astoundingly
bloated at the content layer, which costs way more than any little crypto.
