Performance problems with X4500 using ZFS with NFSv3

When moving a large number of small files onto our X4500 boxes we found very bad performance numbers:

Job local (UFS->ZFS) network (xfs-NFS->ZFS) default mode network (xfs-NFS->ZFS) no cache flushing
copying single 5GB file 6.5s 51.5s 50.9s
removing this 0.0s 0.5s 0.6s
copying 5000 3 kB files 0.3s 257s 16.9s
removing these 0.1s 42.6s 5.2s

(note: This was done via single 1 Gb/s link, thus copying the large file was about line speed)
