maximum memory page size and is limited to no more than 4KB. iSCSI appears to acknowledge every individual block that is sent. That means the most data one can stream without an ACK is 4KB. That means the throughput is limited by the latency of the network rather than the bandwidth.
I am _far_ from an iSCSI expert, but the above should not be true, as it isn't true for other SCSI flavours. If your initiator supports command queuing, it should happily write multiple blocks before stalling on a response.
You can also enable write cache support, but I don't recall if it's necessary to do so on the initiator, the target, or both.
