This is my first use of ZFS, so be gentle. External == ZIL on a

Yeah it's pretty odd. I'd tend to blame the Areca HBA, but then I'd
also point out that the H
I'll take a look at this. ZFS provides outstanding sequential IO performance
(both read and write). In my testing, I can essentially sustain
"hardware speeds"
with ZFS on sequential loads. That is, assuming 30-60MB/sec per disk
sequential
IO capability (depending on hitting inner or out cylinder

It can significantly influence the results obtained in the benchmarks.

I have a lot of people whispering "zfs" in my virtual ear these days,
and at the same time I have an irrational attachment to xfs based
entirely on its lack of the 32000 subdirectory limit. I'm not afraid of
ext4's newness, since really a lot of that stuff has been in Lustre for
years. So a-bench
