I'm running an experiment to see how viable it is to use ARM CPUs for Mastodon. I know they work great for smaller instances, but not sure how well they'd handle 3 million daily Sidekiq jobs. So far they're doing really good once I started to fine tune the settings and lower the thread count to 10 per core instead of 25 per core.
Total cost is about $8.74 per core and they only run Sidekiq services.
@KuJoe Cool! The setup is just missing PoE as power supply and some nice casing.
Is the cost the electricity per month or the investment for the hardware?
Are you using k8s for orchestration?
@jpl I would love to do PoE but while the NICs do supposedly support it, it’s disabled by the board maker for some reason.
The cost is for the hardware (Orange Pi + heatsink case). I excluded the cost of the SD card because I had a bunch already.
Not using k8s but definitely considering it for future tests.
