Hey Folks, my storage backend system is capable of handling writes at around 120MB/sec. Its running the iscsi enterprise target under ubuntu hardy and the open-iscsi initiators are debian etch systems, all connected via gigabit lan. Yesterday I did some load tests and it looks like I won't get any further than 50MB/sec (read and write) on the client side. This is enough for my purpose but what struck me during the tests is that dstat showed network traffic of roughly 80-100MB/sec coming in on the target side. Is this a problem of dstat or does iSCSI really add 100% transportation overhead? I haven't done any tweaks to this side of the setup and the tests were done via dd (writing/reading from/to /dev/zero and /dev/null with the fsync option set).
