That's a fair question Matti!

Encryption we have today, is just the home folder. If encryption of the
entire drive is used, it doesn't take a rocket scientist to know that
the performance slows severely, that more ram is needed and that more
SSD read/write cycles will be needed. This increases the wear and tear
on SSD's, which have a finite lifetime AND more system files need to be
in ram to help avoid excessive delays.

As far as actual numbers....I don't have them. But, a few tenths of a
second can seem like an eternity when the user is sitting there waiting
for the computer to respond to a keyboard command or when
booting/shutting down.
