I think I misunderstood what you said in your first mail.  I thought
you were saying that a file-backed filesystem created with RELENG_4's
newfs(8) behaves differently than later newfs(8).

It's silly, and you were in fact obviously comparing md(4) and vn(4)
performances.  The tests I ran both used md(4).  THus they are

I don't have a RELENG_4 on the same computer as my CURRENT, so I won't
be able to test this.

Sorry for wasting time.
