I deduped a dataset that from ~600G - 396G on a system with 256MB of
physical RAM and a 32GB swapcache. Peak Virt size of 'hammer dedup'
was in the 700MB range. double_buffer was on. Performance was pretty
reasonable and the system was plenty usable the whole time. Don't
remember how long it took,
:Hi all,

:can someone compare/describe need of RAM size by deduplication in
:Hammer? There's something interesting about deduplication in ZFS

The ram is basically needed to store matching CRCs. The on-line
My weekend schedule is too crowded so we will be doing the official
release Monday evening.
HEAD is now 2.11 and we have a 2.10 release branch. 2011Q1 packages
have been built though some work is still ongoing. Preliminary nrelease
builds have succeeded and testing

supermicro opteron server boards work best with Dragonfly off the

environment, but is ZFS possible, or are there any plans to facilitate it if
it isn't?
Regards,
David Crosswell.

It's certainly possible. Nobody's working on it right now, to my
knowledge. I'm more interesting in seeing Hammer grow, so I'm not
that concerned about it.

Yes, I understand that. I'm looking forward to doing something with
Hammer, but I've spoken to a couple of guys at the local Users group
who swear they'll never use anything else but ZFS - got it running on
FreeBSD and I looked at Dragonfly with UFS and Hammer and thought with
ZFS they'd have
