Hehe, nama lijenim mrežašima i linuxašima bez skriptarenja nema ni posla ni života Stalno se nešto štrika i improvizira da se nešto dobije. Možda je vrijeme da otvorim Github acc.

RPi3+ mi daje cca 35-40MB/s. Meni idealno za DHCP, TFTP, log server i sl. korisne mrežne servise. Problem je što je USB spojen na SDIO pa otuda to ograničenje.

RPi4 ima USB3 kontroler zakačen na PCIe interface pa to onda ide full speed i ne opterećuje taj slabašni CPU u UASP modu.
