I have been testing nexenta against opensolaris 2009.06 as an iscsi target / 
storage repository for Xenserver 5.6 using the same hardware and vm 
configuration. The target has two xeon quad-core cpus, 4gb ram and 4 seagate 
drives with opensolaris on the first and a 1tb volume on other three.

Opensolaris seems to perform very badly compared to nexenta when performing 
sqlio tests on a Windows 2008 Server R2 virtual machine. The IOs/s and MB/s 
from opensolaris are apporximately 10% (300 and 20) of the results from nexenta.

Are there tweaks to opensolaris that will increase the iscsi performance and 
explain the difference in performance?

Thanks,

Chris
