When I was experimenting with ZFS over NFS I had similar experiences. Do me a favor and try something that sounds a little out there. On a shell on the ZFS machine set up a looping script that executes an ls on the directory you're writing the file to once every second and watch your transfer rates. I noticed a marked improvement, but I could never determine if it was ZFS or the client NFS implementation. -- Brian On 7/16/07, Steven Schlansker <stevenschlansker_at_berkeley.edu> wrote: > > Claus Guttesen wrote: > >> I'm experiencing what (to me) seems to be strange performance with > >> ZFS.
