I'll keep this real simple: Why did you do this? I hope this was a stress test of some kind. If not: This is the 2nd or 3rd mail in recent months from people saying "I decided to do something utterly stupid with my filesystem[1] and now I'm asking why performance sucks". Why can people not create proper directory tree layouts to avoid this problem regardless of what filesystem is used? I just don't get it. [1]: Applies to any filesystem, not just ZFS. There was a UFS one a month or two ago too... -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
