] getting performance from nfs storage over 10 gb link
I will throw this document into the ring as well.

Even though it's a bit dated, it hits on a lot of the elements that go
into getting the most performance

Hi Gary,
To Skylar:
I will check into those options.
To all:
I can say that tsm performance was better when the same storage was mounted
with the same mount options using a 1 gb

Thanks for the link, hadn't seen
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
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:
gro
lro
rxvlan
txvlan
rxhash
For instance, you can
Tsm server 6.4.3,
RHEL 6.7
4 Dual-Core AMD Opteron(tm) Processor 8220 SE CPUs
128 gB memory
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
watching network traffic
