It is not reasonable to assume that zfs has to retain everything in
memory.
I have a directory here containing a million files and it has not
caused
any strain for zfs at all although it can cause considerable
stress on
applications.
400 million tiny files is quite a lot and I would hate to use
anything
but mirrors with so many tiny files.
Another tought is "am I using the correct storage model for this
data"?
You're not the only one wondering that. :)
