Sorry, but you are misinterpreting what I wrote.
I agree that ib_write_bw / ib_read_bw / ib_send_bw performance results
are not equivalent to iSCSI over iSER. The reason that I included
these performance results was to illustrate that two-sided data
transfers over IB are about as fast as one-sided data transfers.
As far as I know, when using iSER, the FirstBurstLength bytes of data
are sent via two-sided data transfers, and there is no CPU
intervention required to transfer the data itself over the IB network.
