Hi Gerorge,
is it possible that you see 50 Mbytes/sec which is ca. 180 GB/h.
The "sysstat 1" will give you kbytes.
Please post a bit of your "sysstat 1" while the ndmpcopy is running.

Hi, when I ndmpcopy from say, volA to volB on the same head does ndmpcopy use the loopback to do this ?
If so, at what speed can the loopback run at ? I can not seem to go faster then about 20 GB/hr (about 50 Mbits/sec).
I do have GigE NICs in the filer for regular nfs connections to clients.
Thanks, George
