ZFS tuning

So a ran across an article that brings up a good point about tuning the ZFS fs (not the pool)

Two options that should probably be turned off by default are:

zfs set atime=off tank
zfs set sync=disabled tank


The sync=disable should only be turned off if you have a log device (ssd or fast spinning disk) otherwise you can end up with corrupt data pools.
