Personally I would not use zfs, but rather a stripped down ufs with any
non-essential metadata turned off for speed.  Tune it for your most
common files, if you think you need it.

I don't think the overhead of zfs is worth it.

It does lead to a question for the ZFS experts though: can you turn
things like atime modification off in ZFS and if so, does it gain a lot
of speed like it does for other filesystems?

I did *NOT* tune my /var for my last Linux install, and while it isn't
fatal, I can tell the difference when it gets hit a lot. In fact, I'm
running a journaled ext3 fs on it and that gets painful for apps that
create hundreds or thousands of temp files.
