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.
