Hi,

this one: http://www.spinics.net/lists/linux-btrfs/msg47377.html

adds a regression to my test systems with very large disks (30tb and 50tb).

btrfs balance is super slow afterwards while heavily making use of cp 
--reflink=always on big files (200gb - 500gb).

Sorry didn't know how to correctly reply to that "old" message.

Greets,
Stefan
