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.
