Well, I had dedup enabled for a few short tests. But since I have got "only" 8GB of RAM and dedup seems to require an order of magnitude more to be working well, I switched dedup off again after a few hours. > Might be that the DDT tables somehow end up unevenly distributed to disks. My observation was on a 6 disk raidz2. Hmmm, there was another report of even distribution of load on a 6 disk raidz1 (but in fact, in that case the first half seems to have got some 10% to 15 higher load than the second half; the sixth drive showed quite different queue length and latencies and I think these might be caused either by a defect (soft-errors) or another partition being actively used only on that drive).
