Rather idle.
Top shows:
PID USERNAME NLWP PRI NICE SIZE RES STATE TIME CPU COMMAND
22945 root 1 60 0 13M 3004K cpu/6 144:21 3.79% zfs

Having 'fmd' (fault monitor daemon) show up in top at all is rather
ominous since it implies that faults are actively being reported. You
might want to look into what is making it active.
So I'm lead to believe that zfs receive is spending almost 100% of a single
CPUs time doing a lot of
genunix`list_next ...
Or maybe it is only doing 3.7% of this. There seems to be a whole lot
of nothing going on.
Any ideas what is going on here?
Definitely check if low-level faults are being reported to fmd.
