I've upgraded my system from ufs to zfs (root pool).
By default, it creates a zvol for dump and swap.
It's a 4GB Ultra-45 and every late night/morning I run a job which takes
around 2GB of memory.
With a zvol swap, the system becomes unusable and the Sun Ray client often
goes into 26B.
So
I'm currently setting up user directories on a zfs filesystem (Solaris
10) which I then nfs mount on an OpenSUSE 9.3 system.
I have a zpool called zpool1. First, I set up a home zfs volume:
zfs create zpool1/la_home_hpc_users
zfs sharenfs=on zpool1/la_home_hpc_users
Then I create a user
Posting this back to zfs-discuss.
Roland's test case (below) is a single threaded sequential write
followed by a single threaded sequential read. His bandwidth
goes from horrible (~2MB/sec) to expected (~30MB/sec)
when prefetch is disabled. This is with relatively recent nv bits (nv110).

So I removed the zvol swap and now I have a standard swap partition. The

Hello Matthew,
Excellent news.
Wouldn't it be better if logical disk usage would be accounted and not
physical - I mean when compression is enabled should quota be
accounted based by a logical file size or physical as in du?
I'm not saying which one is better just raising the question.

Ya, I agree that we need some additional data and testing. The iostat
data in itself doesn't suggest to me that the process (dd) is slow but
rather that most of the data is being retrieved elsewhere (ARC). An
fsstat would be useful to correlate with the iostat data.
