I am using the ports based ISCSI target deamon from net/istgt. With this port I can get good speeds using my windows 7 machine, it reads and writes at 80 to 90 MB/s on a 1 GB network. If I switch to the native iscsi target using ctld I only get around 30 MB/s read speed, the write speed start high but then drops down to around 50MB half way and then it slowly drops to 40 till the end of the copy. You can see it drop slowly. This is with some iso files, and it is around 10 GB in total. Is there anything I can do to tune this up. regards Johan
