Meaning that nobody can turn off the write cache in linux without deep kernel hackery.

Sounds to me like they are benchmarking the real world rather than trying to favour btrfs by making changes that are unlikely to be viable for anyone trying to run it in production. I.e. they're benchmarking reality.

Sure there are ways that btrfs performance could be improved, but they're not realistically available to mortals selecting "use btrfs for /home" in their Ubuntu "Bleeding-Edge Badger" release.
