Turns out that even in 2016, things like sending a link in an e-mail 
still isn't as easy as it should be. I will be less stubborn next time. :)

So, here are the links, again. First, the 'regular' comparisons

www.audiograaf.nl/misc_stuff/Comparison_on_32-bit_ARM_Raspberry_Pi_B.pdf

The CPUs are an Intel Core 2 Duo T9600 and an Intel Core i7-4910MQ. 
Secondly, these three systems were tested with flac binaries compiled 
with --enable-64-bit-word

www.audiograaf.nl/misc_stuff/Comparison_64_bit_words_32-bit_ARM_Raspberry_Pi.pdf

Finally, I compared the 64-bit word option with FLAC run with, and 
without MD5 sum calculation to verify that the 64-bit word length 
speedup is not mainly because of MD5 sum calculation

Hope this works better :)
