Interesting. That was specifically tested on ZFS in a prior paper referenced by that one and published in 2017: https://www.usenix.org/system/files/conference/

Glancing through, it seems ZFS is about middle of the pack of the analyzed filesystems (BetrFS Btrfs ext4 F2FS XFS ZFS) in terms of performance aging caused by change history. And only BetrFS did not show any aging from these tests and was surprisingly stable throughout. I'm curious if that's changed in recent versions of any the analyzed file systems, I know ZFS has had a major release recently.
