I just migrated my NixOS system from BTRFS to XFS. I've got all my services up and running and I'm already seeing improvements:

- Reduced memory consuption.

- Reduced file fragmentation; The Gossip client LMDB database went from +6,000 extents down to 2.

- Reduced CPU usage. My CPU fan actually turned off for a while :) It turned back on when I launched Gossip, LOL!

I think my laptop is much happier now.
