Dear Andrew,
Thank you for your advice.
We have re-done the tests by
dd if=/dev/zero of=${iSCSI_TARGET_DIR}/bigf bs=1024k count=1000
But it does not make big differences.
The iSCSI target da2 is still much steady than da0 and da1.
The new results are at http://free.cc.kmu.edu.tw/iscsi/iotest.txt
Original results with /dev/random are now at
