It depends on what you're doing.  If you're creating and deleting a
bunch of small files, soft-updates will probably outperform memory-based
because it can combine writes and discard writes that are later made
irrelevant (e.g., writes to a file that is later deleted).  On the other
hand, if you're creating and deleting a bunch of big files, you'll
probably overflow the buffer cache and so prevent it from doing as good
a job of optimizing.
