I can certainly see a very noticeable improvement. .. and btw, just to put that into perspective - I ended up running with that repeated 'dd+sync+rm' in the background for quite a while, and the machine was in no way unusable. I don't think I saw a single "ooh, that feels really dead" case with anticipatory, although I saw several "bad stutter" cases. Of course, with the whole "overwrite" case, things are really much smoother, and I can hardly notice anything happening at all. Although I _do_ get an occasional 200-600ms fsync hickup, and I can tell those very clearly. But if that was the worst I'd ever see, I'd be a very happy person. It's a good goal to have, I suspect.
