Hi all,
I have a 10Gb PCIe NIC, Intel X520-DA1, installed on my desktop and
connected to sfp+1 port with SFP+ DAC cable.
I'm trying to verify the speed of the connection.
I launched a iperf3 server on USRP N310, and a client from my desktop.
The bandwidth is fat from 10Gb. The screenshot below is from my desktop.

Bath mtu of interfaces on N310 and my desktop are set to be 9000.
Many thanks

You'll not get anywhere close to 10Gig when exchanging packets with the
*CPU* on the N310. You only see the high-bandwidth rates when
streaming samples--the CPU is NOT
involved in that at all.
