Hi Gary,
We don't use NFS for our TSM servers, but we have been struggling with NFS
over 10GbE in other areas. While not a universal solution, we've gotten
significant performance improvements by disabling the following NIC offload
options:

Hi Gary

I recently installed an intel 10 gB Ethernet card.
Iperf3 test shown below gives around 7 gb throughput.
However, when running multiple migration and reclamation processes, and
