Teaming Ethernet to USB for performance on pi 3

Tue Jan 03, 2017 6:04 pm

Hello,

I have being reading around on how to "teaming ethernet to usb". I cannot find anything.
Basically I have read this article http://www.jeffgeerling.com/blogs/jeff- ... networking.

From the article, he has benchmarked the raspberry pi transfer speeds. He used a gigabit ethernet to usb apdapter to get the highest speed.

I have two gigabit ethernet to usb apdapters and was wondering if I could "pair" them to get a "faster" LAN transfer speed.

How would I go about doing this? I have read around and found articles relating to debian and to team ethernet to make a fail safe. I don't need a failsafe, I'm looking for more performance.

I'm running raspbian on a raspberry pi 3

Thanks.

Not on the Pi.

The SoC (main chip) in the Pi only has a single USB port. On most models there is another chip which contains a four port USB hub and an ethernet interface that is connected to that single USB port.

What this means is that the on-board ethernet and any USB ethernet adaptors will all be sharing the same single channel. Using a single gigabit adapter will max out that channel. Adding another adapter won't help, in fact it may slow things down as they have to fight for bandwidth.
