I don't use big iron myself, but an idea: what mount options do you use? In particular, I'm thinking about the absence of "noatime". It's absence makes each "read" of a file slower, having to write the time to disk.
Besides that, it seems that you should consider replacing with "lazytime". The access time is then written on bunches and when feasible, not "now". Less wear and faster, even on SSD.
There's no practical use scenario for any Atime recording any more, and there never really was. Nothing depends on it.
Obviously the kernel devs think otherwise. It is going to be the new default. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
