100Mbit is quite flat at 11MB/s;

Not sure how to enable jumbo frames on the rge0. When I use
dladm set-linkprop -p mtu 9000 rge0
I get "operation not supported". PERM is "r--".
Most likely I have to set it with rge.conf, and reboot, but I would need
to rebuild my USB image for that. (unplumb, modunload, modload, plumb
did not seem to enable it either).

Ok I have redone the initial tests as 4G instead. Graphs are on the same

I also mounted it with nfsv3 and mounted it for more iozone. Alas, I
started with 100mbit, so it has taken quite a while. It is constantly at
11MB/s though. ;)

I was following Toms Hardware on how they test NAS units. I have 2GB
memory, so I will re-run the test at 4, if I figure out which option
that is.
I used Excel for the graphs in this case, gnuplot did not want to
work. (Nor did Excel mind you)

impressive numbers indeed. I then looked at the file sizes that iozone
used... How much memory do you have? I seems like the files would be
able to comfortably fit in memory. I think this test needs to be
re-run
with Large files (ie >2*Memory size ) for them to give more accurate
data.
The numbers are indeed "suspect" but the iozone sweep test is quite
useful in order to see the influence of zfs's caching via the ARC.
The sweep should definitely be run to at least 2X the memory size.
Unrelated, what did you use to generate those graphs, they look good.
Iozone output may be plotted via gnuplot or Microsoft Excel. This
looks like the gnuplot output.
