TinyRex Ethernet Performance
kwebster83 , 10-31-2016, 08:50 AM
Hi,
I'm just wondering whether any performance testing has been done on the TinyRex gigabit ethernet?
I'd be really interested to see what the maximum throughput achieved was and over what length of cable.
Regards,
Kevin

Hi Kevin,
I do not have the perfect setup, but I hope this will help you. This is what I run this morning. OpenRex is similar to TinyRex (they both use iMX6).
Connection: My computer (virtual machine 192.168.0.245) -> 2m cable -> Mikrotik router -> 2m cable -> OpenRex (192.168.0.251)
Note: There may be some limitations on my virtual machine settings.

Some time ago we also tested PCIE Ethernet:

Hi Robert,
Thanks for the figures. So I guess roughly speaking, I'd expect to get about 420Mbit send, 120Mbit receive.
I wonder why there is such a difference between the send and receive? Also, the re-transmissions for the first couple of OpenRex sends was quite high - do you know if this is always the case?
I'm looking at integrating TinyRex as a server in an embedded application which primarily has ethernet devices (a couple of very high data rate sensors) so hence I'm keen to know how the module performs.
Kind regards,
Kevin

Yes, I noticed that difference between transmit / receive too. That is interesting.
The numbers may be influenced by my setup. It was a very quick test setup e.g. I am not really sure how the router is set and also using virtual machine as a server is not probably the best (virtual machine could cause re-transmissions). Maybe the best would be try two boards opposite of each other running nothing else just the iperf, but that would take me more time to setup and play with it. When I have some time in coming weeks, I could try it. With this quick answer I only wanted to give you an idea about the numbers - I hope, that helped a little bit too.

Hi Robert,
Your information has been very helpful, thank you. It gives me a very good idea of the baselines that will be achieved and also gives me hope that a lot more performance can be gained - especially on the receive side.
I'd be very keen to hear of any TinyRex to TinyRex performance testing as this is something that I'm also looking at. Almost like a master-slave type setup - maybe with a quad core as the master and a solo/dual as the slaves.
Kind regards,
Kevin

I will double check with Pavol from VOIPAC if they can try it. I do not have TinyRex here (I moved to US and took only some boards - mostly OpenRex). So, shall I ask them to try "TinyRex QUAD <-> TinyRex SOLO", direct connection, iperf application, transfer both directions?

Hi Robert,
Those sound like perfect tests, thank you.
Kind regards,
Kevin
