Thanks for testing this out. As I actually did a similar test last week on my home network I wondered if others would have the same results. From what I can tell you ended up at the same result. Using iSCSI didn't increase performance over what can be obtained using SMB/CIFS. This of course is just on Win XP PRO SP2. Using a different iSCSI target program or a different OS could give completely different results.
