If you're using 4K sectors anyway, then GELI does not create any extra

using 4K sectors, right? ZFS's ashift is set to 12?

Yup, 4k sectors, and I initialised geli telling it to present as 4k
sectors. Am glad to hear that it wont amplify writes - thats what I
assumed, but nice to have it confirmed.
