#2*on Linux.
ZFS on Linux in particular is not representative of ZFS on BSD or Solaris.

#3Why this article had to be segmented into 10 pages is beyond me, however.

#4This is more than a year old. I've been told that btrfs has improved greatly in that time.

#5What is with BTRFS? It stands out in every single test (and not in a good way).

"I've figured out a way to increase our pageviews by 10x!"
For "major" sites there's usually a printable view that consolidates things into one page. I don't see one on this page though.

Kvm (or any overwrite workload for that matter) is the worst possible workload for btrfs because of COW. We have ideas to address this but honestly it's not high on the list.

Not sure what you mean here. They showed that ZFS performed well on linux. Are you saying that ZFS performs poorly on BSD and Solaris?
Love me some ZFS and it works well pretty much everywhere. OpenZFS shows good promise of keeping (bringing) the BSD, Illumos and Linux versions in line with each other.

What kinds of workloads is it designed for then?

I found it just recently when upgraded my VM images storage and BTRFS was still significally slower on HDDs using Ubuntu 16.04. Though I only compared it to EXT4 on LVM with QCOW2 + backing files.
Any idea if there was newer performance comparison for VM storage?
