Ok things look good after the zfs set sync=disabled on the NFS datastore.

We have a single cpu supermicro server with 16 GB mem running 9.0 RC3
And we have a HP ML 110 with 8 GB mem as standby backup server, also on 
9.0 RC3
Both in the same network.

Here are the graphs.

I did a clone from the SM (supermicro) ISCSI datastore to the SM NFS 
datastore. grey block
I did a clone from the SM ISCSI datastore to the HP ISCSI datastore. red 
block
I did a clone from the SM ISCSI datastore to the HP NFS datastore green 
block (not finished but it did go steady on).

Since this is our first NAS/SAN server and vmware environment, i do not 
know if this is good, but it feels ok.
But maybe we should be embarrassed with these results :D
We do not have a HP or IBM SAN solution to test agains.
And this is all over normal GB ethernet, not trunked and so on.
Also no Jumbo frames.

Thanks for the pointers all.
