suffering especially on BTRFS. I have been doing fine without it for years,
it will not help any issue, unless you want read operations to cause writes
and eat space...
### BTRFS
- The above applies, `/etc/fstab` must have `noatime`.
- `compress=zstd:0` may be helpful. It enables zstd compression, which is an
integrated feature of BTRFS, with the default compression level (3 at the time
of writing). The BTRFS devs are most likely wiser than me and can provide a
reasonable balance between efficiency and CPU use.
- The compression will happen either the next time the file is written or can
be manually triggered through `sudo btrfs filesystem defragment -r "$PWD"`
