Thanks for reporting this issue! Could you post your edited /etc/hosts file to include in future Debian images?jdonald wrote: ↑Sun Dec 09, 2018 8:29 amOn code_exec's Debian image with a 3B+ I'm consistently getting 33 seconds for 32-bit and 17 seconds for 64-bit, so it's very close to a 2x speedup but the absolute runtimes are not matching others' results. I'll follow up on the other thread.ejolson wrote: ↑Wed Dec 05, 2018 6:00 amThe Pi 3B+ running in 32-bit compatibility mode completes the computation in 15.43 seconds. Based on rescaling the clock speeds of a different ARM-based single-board computer, it was estimated that the Pi 3B+ running in 64-bit mode should complete this same computation in only 7.49 seconds. If true, that would be a two-fold increase in speed for a particular application just by switching operating systems.
It would be nice if someone who is running a 64-bit operating system on real 3B+ hardware could confirm that this estimate is correct.
It also turns out I was unfortunately mistaken on Docker 32-bit. With packages named both docker and docker-ce, I did not realize I had docker-ce:arm64 installed at the time. Testing again, I'm unable to run any aarch64 Docker images on docker-ce:armhf.
One issue I encountered with the MATE 64-bit image is that whenever I run sudo it says:To fix this I had to edit /etc/hosts.
Code: Select all
sudo: unable to resolve host debian-mate-rpi3
