Linux w/ reiserfs 3.x vs a SUN SAN 7410 running solaris and ZFS

ZFS uses an Extensible hash table dor its directory while most of the other filesystems use a b-tree. I'm no ZFS expert, but perhaps this method degrades for larger directories?

I'm not trying to be a troll, I'm trying to fix the performance problem.

    mkdir /tmp/foo
    cd /tmp/foo
    for ((i=0;$i<6000;i++)); do touch $i; done
    time ls >/dev/null

Perhaps try ext3?

Those are obviously in cache.
