I have a couple of SFF Atom D2700's, so max memory is 4GB. That I've been running as headless servers.... Were FreeBSD 9.1, upgraded to 9.2 last weekend. Though just a couple of 120GB SSDs in them. Been going pretty good. dedup is probably out, though they say L2ARC can help....no plans to add more storage to these. One of the servers is really busy (cacti)....load is usually 12+, since upgrading to FreeBSD 9.2 and switching to lz4....load is often just under 10.... -- Who: Lawrence K.

I'm currently on 9.0 64-bit. I have 2 zfs pools: one is a pair of 16gb thumb drives for / the other is 4x2tb + 2x500gb mirror for 10 or so mount points It runs with zero problems. In FreeBSD 8.x I had to set the arc max to keep from memory starving other processes but 9.0 has been fine. 32-bit was a disaster--I couldn't keep it from crashing. I'm not running dedup. -morgan On Oct 10, 2013, at 1:07 PM, John <freebsd-lists@potato.growveg.org> wrote: > Hello list, > > I'd like to have zfs on my freebsd desktop.
