I have done some performance tests with OmniOS with some tunings,
mainly SMB 2.1 but NFS/ iSCSI/ vmxnet3s should benefit as well from
these settings.
The Hipster 2016.04 should offer similar values than OmniOS 151018.
Maybe you can compare your settings with my settings, especially MTU
and ipbuffers

Hi everyone,
to make the long story short - i 've spent 6 weeks trting really
hard, read tons of doc pages on the internet (get lots of knowledge
to be honest)
so i can get very good results , however unfortunetely i cant get
from iscsi+zfs good results about sequential reading.
Admittedly I have not done any testing of ZFS performance on OpenIndiana.
However, about 4 years ago I went through this very exercise and
tested nearly every available solution (FreeNas, Open-E, Nexenta,
etc.,) and in the end chose Openfiler as my SAN solution. Using 2
NICs, I was able to achieve read speeds of nearly 200MB/s. I don't
recall what the write speeds were, but I am think they were in the
same neighborhood.
Here is a thread post to vmware communities, where I posted my
results: https://communities.vmware.com/message/1986953#1986953
Assuming the storage can keep up, using 4 NIC's in an MPIO round robin
configuration should deliver nearly 400 MB/s.
My white box lab didn't use any kind of fault tolerance. I was only
using 2 500G disks in a raid stripe attached to an LSI controller with
write caching was enabled. The LSI controller managed the disks.
One thing I discovered in this process was the Realtek NIC's vastly
outperformed the Intel NICS. Whether the issue was on the ESXI side or
the Openfiler side, I am not sure. I swapped both sides out with
Realtek. OpenFiler however didn't natively support the Realtek NICs so
I had to install my own drivers.
I have read the freebsd project has done some tuning to get ZFS to
perform better. There are also some tunable parameters in illumos
which may possibly help. See here:

Hope that helps,
Michael
