In common with a lot of people I don't have much faith in SU+J. Do you
have a source for gjournal being deprecated? I don't see any mention of
it in the man page.

I don't understand why you think that. My point was that losing random
files from everything can be far more disruptive than losing files from
a single mountpoint.

I was really more interested in whether ZFS (with ARC) is faster than
UFS with FreeBSD's own file caching. A lot of people say that putting
an OS on SSD gives a significant speed-up. 16GB should be more than
enough to keep the important system files in memory, so it sounds like
smarter caching might be useful.
