Won't disabling ZIL minimize the chance of a consistent zfs-
filesystem
if - for some reason - the server did an unplanned reboot?
ZIL in ZFS is only used to speed-up various workloads, it has
nothing to
do with file system consistency. ZFS is always consistent on disk no
matter if you use

Don't take this numbers too seriously - those were only first tries to
see where my port is and I was using OpenSolaris for comparsion, which
has debugging turned on.
Yeah, ZFS does a lot of extra work with debugging on (such as
verifying checksums in the ARC), so always do serious performa

I'm all set for doing performance comparsion between Solaris/ZFS and
FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I
think I'm ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB

Or if you do want to use bfu because you really want to match your
source code revisions up to a given day then you will need to build the
ON consolidation yourself and you an the install the non debug bfu
archives (note you will need to download the non debug closed bins to do
that).
