A simple test that I like doing to measure performance data is like:

time dd if=/dev/zero of=/mountpoint/dummyfile bs=1M count=1024

That writes a 1 GB file from the /dev/zero and tells you how long it
took. I'd be interested to see the differences you measure between iSCSI
and local storage. 

Of course, I am aware that this is just one simple and limited test, but
it gives an idea anyway.
