On a related note: How fast do CPU cores clock in your installation: /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
Cpufreq scaling should scale between 800 and 1200 MHz but at least the Armbian dev currently working on Espressobin reports the CPU cores being limited to 800 MHz for whatever reasons (by examining the .dtsi I wondered that OPP for dvfs/cpufreq scaling are currently missing but I didn’t had a closer look).
The older Armada 38x SoCs (Cortex-A9 and clocking up to 1.6GHz) are known to saturate a 2.5GbE link so there’s still some hope 😉
