Resto basito dal tempo di avvio e dal fatto che parte anche l'interfaccia grafica Xhttp://dmitry.co/index.php?p=./04.Thoughts/07.%20Linux%20on%208bit
How fast is it?
uARM is certainly no speed demon. It
takes about 2 hours to boot to bash prompt ("init=/bin/bash" kernel
command line). Then 4 more hours to boot up the entire Ubuntu ("exec
init" and then login). Starting X takes a lot longer. The effective
emulated CPU speed is about 6.5KHz, which is on par with what you'd
expect emulating a 32-bit CPU & MMU on a measly 8-bit micro. Curiously enough, once booted, the system is somewhat usable. You can type a command and get a reply within a minute. That is to say that you can,
in fact, use it. I used it to day to format an SD card, for example.
This is definitely not the fastest, but I think it may be the cheapest, slowest, simplest to hand assemble, lowest part count, and lowest-end Linux PC. The board is hand-soldered using wires, there is not even a requirement for a printed circuit board. 

Ciao vs Antonio Guidetti
