Yes, allthough my RAIDframe performance test results show that the effect
decreases with larger block sizes.

I can think of two ways to acheive this (each of which may be absurd given
better knowledge of fs internals than I have): Either a per-process switch
disabling atime updates or a way to obtain a read-only clone of a block
device which can be mounted ro,noatime.

Maybe fss is a way to go, but it's still marked experimental in 6.0 and
taking the snapshot may outweigh the later performance gain.
