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