The RPi seems to beat the Bbone quite clearly with a ration of 6 : 10 It is very apparent (when unpacking for instance) that the Bb shows a much more pronounced 'hickup' behavior, unpacking 40-60 files and then most probably doing disk IO. Swapping the MFCards does not change the situation at all. Can anybody out there suppprt this observation and/or explain it? Cheers, Werner
