(Not a reasonable comparison.) In checking on that, I ran into the following information: https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-codes/README.md only shows one revision for 3B+: Code Model Revision RAM Manufacturer . . . a020d3 3B+ 1.3 1GB Sony UK . . . Under RaspiOS the revision code shows up via: cat /proc/cpuinfo It was released in 2018. (See https://en.wikipedia.org/wiki/Raspberry_Pi .) >> RPI4B.

The figures are in megabytes. So, on the Devuan, I can consistently obtain 18.x megabytes transfer using FTP or Samba.

The case has a fan, it is set for 50degC turn on (via GPIO). For FreeBSD there is not even an attached USB; nothing is on that bus. > === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
