A week ago I received a Sabre Lite SD board. The Sabre Lite board I received has very interesting characteristics:

 

I installed Ubuntu Linux with the following kernel:

The first test I did, was testing the on board Gbit Ethernet. To run the tests I used iperf3 (take a look at Using iperf to measure network performance)

As first tests I was interested in the maximum speed the board can reach while using TCP, an in the data loss while using UDP. I connected the Mac Mini and the Sabre Lite Board, back to back using the Gigabit Ethernet interface, then I installed iperf on both the systems.

TCP Maximum speed test

On the Sabre run:

On the Mac Mini run:

And the results

Then exchange the roles, adding the -R switch to the previous command line

In both cases the performances are interesting, the Sabre Lite can receive more than 500 Mbits/sec and can send more than 400 Mbits/sec.

 

UDP Data Loss

On the Sabre run:

On the Mac Mini run:

The above command make a stream with a target bandwidth sets to 500Mbit/sec. The results are the following:

Then exchange the roles, adding the -R switch to the previous command line

In both cases (at 500 Mbits/sec) the average of Lost datagrams are good enough.

 

Using the iperf command line switcehs, you can do very interesting tests on your specific architecture. This is only a simple example…
