A few things come to mind... 1. A lot better than...what? Setting the recordsize to 4K got you some deduplication but maybe the pertinent question is what were you expecting?
2. Dedup is fairly new. I haven't seen any reports of experiments like yours so...CONGRATULATIONS!! You're probably the first. Or at least the first willing to discuss it with the world as a matter of public record? Since dedup is new, you can't expect much in the way of previous experience with it. I also haven't seen coordinated experiments of various configurations with dedup off then on, for comparison. In the end, the question is going to be whether that level of dedup is going to be enough for you. Is dedup even important? Is it just a "gravy" feature or a key requirement? You're in un-explored territory, it appears. On Fri, Apr 23, 2010 at 11:41, tim Kries <tim.kr...@gmx.de> wrote: > Hi, > > I am playing with opensolaris a while now.
