Delete unused BTRFS snapshots. Enable compression by setting flags on /etc/fstab and run btrfs defrag to compress existing snapshots.

Great suggestions, that will absolutely be my tomorrow project!

I use BTRFS with zstd compression at the default level basically everywhere and it's great. I don't notice any performance difference but I have a lot more storage.

Defrag will remove the CoW of the snapshots tho. It will definitely make things worse. I'd say remove (but keep at least one per subvolume) snapshots, set the flags, and wait until the snapshots trinkle down
