Revision as of 21:36, 11 May 2017
Since there is no official 64bit Rasbian distribution for the Raspberry Pi 3, there has been a lot of discussion if a 64bit version would actually give any performance benefit.
I try to answer the question by performing BWA-0.6.2 benchmark on various kernels and distributions.
I have added a heatsink and fan to the RPI3, to allow for non-throttled performance.
Debian bootstrap is used for building and testing
