Hi Gary

What performance does Iperf3 get when you run it on your NFS server?

There is a lot that is going on that has very much to do with your disk
configuration on both your TSM server and the NFS server.

Have you looked at a tool like iometer to see what performance you can
squeeze out of your storage subsystems?

Have you seen this?
