Title: Best transfer rate from LAN
Post by: otyugh on March 30, 2018, 01:05:57 AM
Hey,
using an NFS transfer, I never do better than 10Mo/s (incoming to the A20).
...Which is better than the 1Mo/s I had on Rpi, which is not as good as it could be maybe ?

The best "pikes" I get (monitoring it with nethogs from the A20-micro using ssh).

CPU usage is not that hight :

Any idea experience with it out of the box ? I didn't tweak anything, pretty much everything is "default".

The A20-OLinuXino-MICRO has 100Mbps Ethernet controller and the theoretical maximum is 12.5MBps. How much transfer you expect?

If you need more than that consider one of our boards with 1000Mbps Ethernet (Gigabit Ethernet) controller like A20-OLInuXino-LIME2 or A20-SOM204-EVB.

Best regards,
Lub/OLIMEX

I'm gonna make myself famous there for my fails  ;D
I mentally assumed it was 100MBps.

Thanks for the clarifications :)
