My machine is about 10 years old so I was more concerned than normal
about the CPU usage. If lz4 was an option I would've gone with that, but
according to the Arch wiki or some other locations lzo was basically the
fastest option.
Since mail is mostly text I occasionally recompress that. I haven't
figured out how to use 'btrfs filesystem defragment' to choose the
compression level for zstd.
