[storage-discuss] COMSTAR performance

Hello, 
I followed guide in comstar admin guide and established iscsi target over my zfs pool of seven drives (one of them as spare). Finally, I connected this storage to windows server (2008 x64) and performance I've got is starting at 30M/s (write) slowing down to 15M/s.
This isn't good result I think, RAID5 hardware volume + linux iscsi target on ext3 (same hw) resulted in around 35M/s standard write speed.
What should be wrong?
