If so, very wired. I just run open-iscsi and IET/tgt with two boxes connected via a GbE switch with the same iSCSI parameter sens:/home/fujita# ./ltp-full-20061222/testcases/kernel/io/disktest/disktest -PT -T30 -h1 -K8 -B32768 -pL -ID /dev/sdd - tgt | 2007/11/26-17:39:24 | STAT | 2184 | v1.2.8 | /dev/sdd | Read throughput: 53706752.0B/s (51.22MB/s), IOPS 1647.0/s. - IET | 2007/11/26-17:44:21 | STAT | 2248 | v1.2.8 | /dev/sdd | Read throughput: 42860544.0B/s (40.88MB/s), IOPS 1316.0/s. BTW, you need to change several parameter with tgt since the tgt default paramaters are different from the IET paramaters. _______________________________________________ Stgt-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/stgt-devel
