[How to do instruction] 9.0.6 on Pi 4B, 3B+, Zero 2W

[the_bertrum]

I run a two 4b, and a 3a. I also ran on a zero for many years before 32bit died .
In general playback, I see no performance difference. Updating the software or rebuilding the library are slower on the lower powered devices, but the difference between a 4 on ethernet and a 4 on wifi is bigger than the difference between a 4 and a 3 for example.

In short, performance is fine
