Btrfs is notoriously ill-adapted to database workloads. Although interestingly, some people seem to run Postgres on ZFS just fine, even without disabling copy-on-write like one is advised to do for btrfs.
- ravi-delia 6y agoA lot of it comes down to the default settings. ZFS is just well tuned for a workload like that, and I believe automatically detects some features of the disk it's on. BTRFS by comparison is worse off by default, but if you tune it right it runs pretty much the same.
