Armbian Mainline kernel vs Legacy kernel - GbE - OPi Win A64

Recommended Posts

I was curious to see how Mainline kernel performs on GbE test against a Legacy kernel.

 

For the Armbian side i chose the nightly dev Armbian_5.27.170602_Orangepiwin_Ubuntu_xenial_dev_4.11.1_desktop.img  (Desktop) and for the Legacy i chose my own build with all  "Bells and whistles" (full Desktop, hdmi, camera, bt and wifi).

I did not optimized Armbian Mainline, just installed and run stock. For the Legacy i optimized as usual. If there is some optimization to do on Mainline side, i missed.

 

I have some observations about the board and results:

* Board is without Heat-sink,

* Legacy subsequent test got lower values, i suspect it runs hotter than Mainline, maybe due to HDMI, camera and BT enabled, drops about 30~50 MBits/sec,

* After Mainline installation, the next boot came without HDMI output, so i had to guess which IP was assigned without looking at router (OK, we know it is a development Image),

* Board act as a Server (iperf3 -s) and my ultra fast Duo core Intel box as a client.

* Both Image are build with gcc 6.3

 

Armbian Mainline kernel 4.11.1 results:
