I write images on Hetzner using Packer, but it becomes quite a pain to clean them up manually, luckily there's an API, so I built a quick script that does two things:
It then compares the 2, and offers you to delete the unused images.

| # Maximum number of arenas to use for automatic multiplexing of threads and arenas. | |
| # The default is four times the number of CPUs, or one if there is a single CPU. | |
| narenas: 2, | |
| # Enabling jemalloc background threads generally improves the tail latency for application threads, | |
| # since unused memory purging is shifted to the dedicated background threads. | |
| # In addition, unintended purging delay caused by application inactivity is avoided with background threads. |
