It's new, considered experimental and not well tested. In my initial testing with RAID5, it was so slow as to be unusable. The IOPS too low and latency too high compared to soft RAID1, single drive, or hw RAID 5. I didn't consider using it seriously. Now your testing shows a more significant problem. Are you working with someone to bring your RAID1 changes in tree? The complete, understood improvements should be individually labeled and committed, one by one. Chris
