As for ZIL - even if it is used with the in-pool variant, I don't
think your setup needs any extra steps to disable it (as Edward likes
to suggest), and most other setups don't
Hi Nathan,
You've misunderstood how the Zil works and why it reduces write latency for
synchronous writes.
Since you've partitioned a single SSD into two silces, one as pool storage and
one as Zil for that pool, all sync writes will be 2X amplified. There's no way
around it. ZFS will write

I chopped into a few slices - p0 (partition table), p1 128GB, p2 60gb.
As part of my work, I have used it both as a RAW device (cxtxdxp1) and
wrapped partition 1 with a

Why are you parititoning, then creating zpool,
The common case it's often because they use the disk for something

Hi folks,
some extra thoughts:
1. Don't question why. :) I'm playing and observing, so I ultimately
know and understand the best way to do things! heh.
2. In fairness, asking why is entirely valid. ;) I'm not doing things to
best practice just yet - I wanted the best performance for my VM's,

Overall, the pain of the doubling of bandwidth requirements seems like a

persist and see what I can get out of it.
I might also speculate that for each rewritten block of userdata in
