That comparison is relevant only if the system has nothing better to do
than wait for the page out/in.  A few systems probably don't.  Most, I
suspect, do, and if there _is_ something else the CPU could usefully be
doing, I suspect spending the (scarce) cycles there is preferable.

At least for most systems.  There certainly is a place for allowing the
admin to insist on encrypted swap even on slow machines.
