i think APU2C4 is best choice (not ARM), later you have Pine ROCKPro64 (RK3399 based - standard Pine do not support hardware encryption - see cpu spec) and Firefly - also RK3399 but pricier option RpiX is really bad choice.
among all solutions i considered for network things APU2C4 was always best (based on Intel 210AT) _ Zbyszek Żółkiewski > Wiadomość napisana przez Carlos López <carlopm...@gmail.com> w dniu > 26.08.2018, o godz. 11:26: > > My only requirements are: > > a/ OpenBSD well hardware's supported > b/ Best network throughput
