MFCard access speed difference between RPi and Beaglebone

Hi

trying to nail down the crash and core dump in Python when importing 
ctypes I did a parallel build of python on both systems with the same 
SVN rev 246947 of kernel.

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
