comparison NanoPi NEO Kernel 3.4 to 4.4

[mstroh]

Hi

 

i did some comparison of NanoPi NEO Kernel 3.4 (Jessie) and kernel 4.4 (Stretch).

 

- Looks like the temperature limit controlling of 4.4 is not working as good as 3.4

   (on 4.4 Kernel the CPU reaches more than 85 °C!)

- GPIO (wiringPi) has less performance (-4%)

- SPI has better performance (10%)

- CPU performance is ~6% better (nbench, maybe the newer compiler)

- consumption is besser on Kernel 3.4, especially on halt state

 

I did a fork for wiringpi Library to make it work on Armbian Jessie and Stretch

(so far only for NEO)
