That's a handy feature. I've added a couple of such comparisons:

Disabling NCQ looks like a very tiny win for the multi-stream read case. I
found a much bigger win, but i was doing RAID-0 instead
There are *lots* of options for configuring a Thumper, what you choose really
depends on the kind of performance you want. I found these sites incredibly
helpful in working out what was best for us:

Gaaah, no idea what happened to that. It looked ok in preview, but it seems
the message board is adding odd characters to my text. Trying again:

Hi all
I've a Sun X4500 with 48 disk of 750Go
The server come with Solaris install on two disk. That's mean I've got 46
disk for ZFS.
When I look the defautl configuration of the zpool
zpool create -f zpool1 raidz c0t0d0 c1t0d0 c4t0d0 c6t0d0 c7t0d0
zpool add -f zpool1 raidz c0t1d0 c1t1d0

Thanks for the tips...

I've use
mkfile 10g
for write and I've got same perf with 5*9 or 9*5.
Have you some advice about tool like iozone ?
Regards.

I'd take a look at bonnie++

Also filebench:

You'll see the most difference between 5x9 and 9x5 in small random reads:
