iscsi performance to a RAM disk iscsi target using the same fio
parameters, yields a 1GB/second throughput for both read and write
, etc?

iscsi performance to a RAM disk iscsi target using the same fio
defaults to if not
specified but if it is 1 that won't yield good performance.

Yes, using open-iscsi with tgt

Yes, using open-iscsi with tgt as the target side.
I used fio with the following job file. I only used 1 job (thread) because
I want to see the max that a single job can read at a time. Even by
maximizing the MaxXmitDataSegmentLength and MaxRecvDataSegmentLength, I
dont see much difference.
Are you using linux for the initiator? If so, what is the throughput you get
from just using this open-iscsi initiator connected to tgt with a ram disk?
I just installed RBD here for work, so let me check it out. What io tool are
using and if it is something like fio could you post the
