FreeBSD-current supports async writes.  You are likely going to see
a bigger difference on small feeds because you can cache the entire
directory structure.  In order to mount a filesystem for async writes
on -current you can do:

mount -o async /dev/xxxx /fs

You can change a filesystem from sync to async by:

mount -u -o async /fs

or from async to sync by:

mount -u /fs

Alot of people have run filesystems on FreeBSD -async with little
trouble (even on crashes), but the usual message saying that
you are playing with fire applies...  BTW, Hopefully 2.2 will
have an LFS to play with!!!  (A filesystem relatively immune
to corruption.)
