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 bwa, so the same binary is used for all distributions

debootstrap --no-check-gpg --variant=buildd --arch=armhf unstable arm32-sbuild http://ftp.debian.org/debian
debootstrap --no-check-gpg --variant=buildd --arch=arm64 unstable arm64-sbuild http://ftp.debian.org/debian
