A year ago I set up Ubuntu server with 3 ZFS pools on my server, normally I don’t make copies of very large files but today I was making a copy of a ~30GB directory and I saw in rsync that the transfer doesn’t exceed 3mb/s (cp is also very slow).
What is the best file system that “just works”? I’m thinking of migrating everything to ext4
EDIT: I really like the automatic pool recovery feature in ZFS, has saved me from 1 hard drive failure so far

For BTRFS since it use of Copy of Write, it is more vulnerable. As metadata needs to be updated and more. Ext4 does not have CoW.
This is where theory and practice diverge and I bet a lot of people here will essentially have the same experience I have. I will never run an Ext filesystem again, not ever as I got burned multiple times both at home/homelab and at the datacenter with Ext shenanigans. BTRFS, ZFS, XFS all far superior and more reliable.
I run BTRFS my self.
And I agree BTRFS , is superior.
