I'd use a real benchmark utility instead of just dd. Aslo keep in mind that this test won't do much i/o if you have compression enabled. CIFS may or may not use SYNC writes, iSCSI will (normally) use SYNC writes, so that will have some impact, but for reads, they shouldn't matter. In most (or all?) circumstances, reads should be faster than writes.
