I'm very interested to use

Processing with a single-board computer like Raspberry Pi, Cubieboard, PCDuino, Pandaboard, BeagleBoard Black etc. I would run Processing sketches on these board, not develop them. The development is already made in a normal PC.

Experiences about this? 

Does Processing sketches run fast in these little boards? Which is the best SO to use with Processing (ubuntu, android, raspbian etc)?

Thanks.
