At the time of writing that post, no, I didn't run zpool iostat -v 1. However,
I run it after that. Results for operations of iostat command has changed from

and from 3 to something in between 200 and 450 for a

A question: why do you want to use HW raid together with ZFS? I thought ZFS
performing better if it was in total control? Would the results have been
better if no HW raid controller, and only ZFS?

At this point, ZFS is performing admirably with the Areca card. Also, that
card is only 8-port, and the Areca controllers I have are 12-port. My chassis
has 24 SATA bays, so being able to cover all the drives with 2 controllers is
preferable.
Also, the driver for the Areca controllers is

Ross,
No need to apologize...
Many of us work hard to make sure good ZFS information is available so a
big thanks for bringing this wiki page to our attention.
Playing with UFS on ZFS is one thing but even inexperienced admins need

Okay, after doing some testing, it appears that the issue is on the ZFS side.
