Any reason you chose lzo over zstd? >=20 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.
