IET performance is very good, given that one has good backend storage  
performance and good networking (use bonnie++ or iozone or whatever  
disk benchmark works for you and iperf for network).

Get the local disk and network performance to the best level you can,  
then setup IET. It is frustrating to work the other way around. To  
test IET performance test it on the initiator side with a disk  
benchmark tool that tests random as well as sequential performance  
with standard block sizes (4k 8k 16k 64k) and use a reasonable number  
of outstanding IOs like 4.
