In snac on an ancient Raspberry Pi news, I switched from XFS to Btrfs and my memory pressure issues are now a thing of the past. As a bonus I can use snapshots for backups instead of taring up the many small files that snac generates (it has no traditional database).

I tried tuning various parameters but after some reading came to the conclusion that lots of small files with very little RAM is about the worst case scenario for XFS.
