[...] OK, so you reject softupdates because it took time to mature and you assume it stopped improving when you stopped paying attention. How long do you think it will take for HAMMER to mature? Realistically? How long will HAMMER be "a huge source of bugs in the system" before it stabilizes? Think back to when you started DragonFly. How soon did you expect it to overtake FreeBSD in SMP performance? And how long did it actually take? Actually, it never happened - DrangonFly doesn't scale at all across multiple cores, while FreeBSD 7 leads the pack. Perhaps you should adjust your expectations a bit. I don't doubt that HAMMER will be a very interesting file system when it's stable, but I doubt very much that will happen any time soon. In fact, I think it will take about as long for HAMMER to mature as it took for softupdates and SMPng. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
