Thank you mailinglist,
That was a lot of info. First of all, I don't think this is a cpu issue
since the cpu is mostly idle while copying.
Second, I tried the hacks in loader.conf and the other ones mentioned in the
beginning of the thread. Allthough perfomance is somewhat increased, it is
still h

Based on my experiences at home, I converted my desktop at work to
pure ZFS. The only issues I've run into have been programs that
extensively use mmap(2) - which is a known issue with ZFS.

Currently, mirrored. I'm considering raidz1 at home. Note that my
work system is a single pool, whereas I'll use a separate pool for
root at home.

I would disagree. In this case, the op's most serious problem is a

I can tell you what the problem is right now, actually. ZFS performs very
poorly on low performance CPUs (i.e. your Atom N330). Try the same system with
a different CPU and you'll get a different result. It's not a lack of
bandwidth on your bus, memory, or disks, and it's not exactly the chec

Thanx for all the replies.
The hacks sounds good until 8.2 is released however, regarding this upgrade,
is the on-disk format the same? Can I just add the pool to a new install (of
8.2-RC) and expect higher performance? Or do I need to recreate the pool
with the newer versions of the utilities?

Hello everyone,
This is my first mail on the mailinglist and I very much appreciate this
option of getting some help.
I have a question regarding zfs on freebsd.
(I'm making a home server)
This afternoon I did a "zpool create data mirror ad4 ad6" Now I'm copying
things from my ufs2 disk into the
