did you install Napp-it?
do you have spare disks, to add as log (ZIL) or cache (ARC) ?
to add cache (arc)
zpool add tank cache c4t2d0
zpool add tank cache c4t3d0
where tank is the pool name, and c4t2d0 and c4t3d0 are disks, cache cannot be mirrored.
to add log (zil)
zpool add newpool log mirror c0t6d0 c0t7d0
where newpool is the pool, and c0t6d0 c0t7d0 are disks

Thanks, but I really like the gui to configure, helps me to understand zfs concepts. Does screenshot above help to clarify my problem?
It says to add disks to pool, but when I add disks to pool, I don t see option to make log or cache disks.
