In real world scenarios, where file based backups fail, one needs to add at least lvm.

And only than those benchmarks would be more interesting to me.

Be specific. Why do you need LVM? What for, what do you do with it?

Secondly: are you aware that ZFS includes what LVM does on Linux, and so you don't need a separate tool for it? This makes the comparison tricky but it's important to consider.
