While we're on it I'll post mine too.

PentiumIII 700Mhz / 256MB RAM / 120GB HD

-CURRENT as of June, 16th (all but /boot on zfs)

zfs_load="YES"
vfs.root.mountfrom="zfs:tank/slash" 
vfs.zfs.prefetch_disable="1"        # performance
vfs.zfs.zil_disable=1               # memory hungry
vfs.zfs.arc_min=8388608             #
vfs.zfs.arc_max=33554433            #
vm.kmem_size=134217728              # quite high ?
kern.maxvnodes=8000                 # quite low ?

No problems so far
 - running xorg, firefox, konqueror, gimp together every day
 - rebuilding the whole system on zfs
 - rsyncing 30GB of data onto the disk, copying it around
 - scrubbing the whole pool

I didn't yet benchmark/optimize for performance thought.

Comments ?
