Following some advice from our base-images master @nghiant2710, I was trying out the resin/aarch64-debian base image on the Samsung ARTIK 710, as opposed to the armhf version that it is deployed default. AArch64 (that is 64-bit ARM) support seems to be experimental in most distribitions, but it’s worth starting to play around a bit.
FROM resin/aarch64-debian
ENV INITSYSTEM on
RUN apt-get update && \
apt-get install -yq --no-install-recommends \
sysbench \
&& apt-get clean && rm -rf /var/lib/apt/lists/*
CMD while : ; do sysbench --test=cpu run --num-threads=1 ; sleep 10 ; done
The resin/artik710-debian or resin/armv7hf-debian images were the ones to test against (they are pretty much the same).
The results are as follows:
ARMv7hf
sysbench 0.4.12: multi-threaded system evaluation benchmark
Running the test with following options:
Number of threads: 1
Doing CPU performance benchmark
Threads started!
Done.
Maximum prime number checked in CPU test: 10000

total number of events: 10000
total time taken by event execution: 175.0733

The difference is 175.1s vs 11.4s, which means the AArch64 version is about 15.4x faster than the ARMv7hf version. This would be a good enough reason to start checking out migrating to 64-bit ARM, I guess.
So far only Debian has AArch64 version on resin.io, see the caveats and listings in our docs, hopefully as distros has more experience with the architecture, there will be more choices as well!
