what about BTRFS since it's the successor of ZFS?
BTRFS is NOT the successor to ZFS. It never was. It was completely new file system developed by Oracle Corp. For some reason, Oracle seems to have lost interest in it. Red Hat has deprecated and, in all likelihood, BTRFS will go the way of Solaris and SPARC chips: ride into the glorious history of the computer science. However, BTRFS has never been widely used, not even among Fedora users like me. BTRFS was suffering from problems with corruption and performance. This is probably not the place to discuss the inner workings of snapshots, but it is worth knowing that snapshots drastically increase the IO rate on the file system - for every snapshot. That's where the slowness comes from.
