I would test the effective network bandwith with iperf. Then I would test the speed of the cinder backend by mounting the volume locally and running, for instance, iozone.
Finally, I would test the performance of the iSCSI backend by mounting the volume on the compute node (or another node) via iSCSI and running iozone on top of it. But I have to admint I don't have much experience with iSCSI :) .a.
